This may be repeated, but none of the existing answers solved my problem.
So, I'm using Python 2.7, and I get this error (title) whenever I try this:
number = int(raw_input('Number : '))
I tried this in Sublime Text 2, compileronline.com and in codecademy; it fails in the first 2 of this sites. It works on codecademy and in the terminal compiler, but I can't understand exactly why it is failing.
The issue here is that Sublime text 2's console doesn't support input.
To fix this issue, you can install a package called SublimeREPL. SublimeREPL provides a Python interpreter that takes in input.
And as for compileronline.com, you need to provide input in the "STDIN Input" field on the lower right of the website.
try:
value = raw_input()
do_stuff(value) # next line was found
except (EOFError):
break #end of file reached
This seems to be proper usage of raw_input when dealing with the end of the stream of input from piped input.

This is my code in python3:
import heapq
myQueue = []
n = raw_input()
try:
num = int(n)
if num<=100000 :
arr = input().split()
for i in range(num):
heapq.heappush(myQueue, arr[i])
print(myQueue[0])
except (NameError, ValueError):
print("Wrong Input, N should be under 100000")
except IndexError:
print("Inputs is less than actually required")
except EOFError:
print ("Error: EOF or empty input!")
I am trying to implement priority queue.
But I am facing this EOF Error while solving this problem on GUVI.
Output:
Error: EOF or empty input!
The tried to catch the error using except EOFError, but that will just make my program run but does not solve input problem right.
I even tried to run this piece of code on Sublime text editor as well as Vs code,
where it runs just fine, Correct Output.
I don't understand, is there a problem in my code or That Online Platform.
I even tried to search the answer on their Q&A platform of GUVI, I found similar question but no one has answered it.
And this is not just for this piece of Code but I found the same error for many before.
Could ANYONE help me, Please!
Thanking you in advance.. :)
EOF error occurs if the input is not provided.
In case of most of the online compilers you need to provide the inputs before running the code.
With that said, while your are trying to access the input via raw_input() there will be no input supplied resulting in the above error.
To avoid this, error supply inputs before running your code like below
Also, I can notice that you are using raw_input() and input(). Please note that raw_input() can be used if you are using Python 2 and input() if you are using python 3 correspondingly.
This piece of code is supposed to find account balance after withdraw from bank(fee=0.5).
wd,ac=raw_input().split(" ")
wd=int(wd)
ac=float(ac)
if(ac<wd):
print(ac)
elif(wd%5==0):
if(ac>wd+0.50):
print(ac-wd-0.50)
else:
print(ac)
else:
print(ac)
I got a Runtime NZEC Error while submitting on codechef. I am newbie and had searched for resolve and had used split(" ") in place of int(input()), which I had tried previously, but the problem still occurs.
Geeksforgeeks says:
"In python, generally multiple inputs are separated by commas and we read them using input() or int(input()), but most of the online coding platforms while testing gives input separated by space and in those cases int(input()) is not able to read the input properly and shows error like NZEC"
Given that I've tried to account for that... What is wrong with my code?
It looks like an error with your raw_input statement. Remember that, in python 3, raw_input doesn't exist any more. If you changed it from raw_input to input, then the code works just fine.
name = input("Hi. What's your name? ")
print("name")
print("Hi,", name)
input("\n\nPress the enter key to exit.")
It says multiple statements found while compiling a single statement
I'm using a book and tried many different things. Also, I'm a noob at this as you can tell. If you have any suggestions that'll be great
Your code is fine, assuming you are using python 3, but you need to type (or paste) each line, one at a time. Based on what you are seeing, I suspect you are putting it all in at once, without a new line after each line.
If you are using python 2, you'll need to use raw_input rather than input, like this:
name = raw_input("Hi. What's your name? ")
print("name")
print("Hi,", name)
input("\n\nPress the enter key to exit.")
So couple of things:
print("name") will not print the name you captured from the last variable but a string that says name
print("Hi,", name) prints ('Hi,', 'Dmitry') which is probably not what you want, instead do this: ', '.join(["Hi", name]) There are probably other Python 3 conventions but I work in Python 2 so I don't know them all off the top of my head.
input("\n\nPress the enter key to exit.") not sure of the purpose of this line. Seems like a stray line from a block of code and it's not being assigned to any variable. Furthermore it throws an error SyntaxError. What book are you using if I may ask?
You can check the Python version in the HELP>about IDLE tab of IDLE editor or Shell - you seem to be using python 2 as others have stated
If you are able to enter and run one line of code at a time, followed by the next line then you are using the Shell, not the IDLE editor
You should be able to paste the code you have in question into IDLE editor and run (F5) - you should be prompted to save before it is run in the Shell.
I am really new on python and try to find a good IDE
My friend suggest me sublime text3.
But when I try to write some code, it come up a question:
I try to write a code that will read the line from user input.
import sys
a = sys.stdin.readline()
print (a)
At beginning I expect some cmd jump out and let me type something to let my program read.
But there's nothing happen....
Can someone tell me that can SublimeText read user input?
or did I do something wrong....
(I find out that there is a post discuss about 'Using sys.stdin.readline() to read multiple lines from cmd in Python'
Using sys.stdin.readline() to read multiple lines from cmd in Python
but I'm not sure if this is the case for sublime.....)
Hi everyone again.
Sorry for the miss leading title and thank you for answering my question again!
DYZ point out the question I would want to ask, and actually I also try package "SublimeREPL". However, it's not working :(( (the figure show it)
I also try my code on terminal and it works...
Can some one tell me where did I did wrong? or maybe I shouldn't do this on Sublime..
thank you guys again and sorry for confusing!
enter image description here
Correct me if I misunderstand what you are trying to do, but to get user input in python theres no need for importing sys, just use raw_input(). For example:
x = raw_input("enter something: ")
print "you entered", x
This program (written in sublime by the way) when run in the command prompt, produced the following output:
python user-input.py
enter something: hello
you entered hello
In this case I entered "hello". If you don't need a prompt, just don't pass any parameter to the raw_input method.
Let me know if this wasn't what you needed or if you need any clarification.
See this question on using stdin: How to finish sys.stdin.readlines() input?
Example below (From the Q):
>>> import sys
>>> message = sys.stdin.readlines()
Hello
World
My
Name
Is
James
Bond
# <ctrl-d> EOF sent
>>> print message
['Hello\n', 'World\n', 'My\n', 'Name\n', 'Is\n', 'James\n', 'Bond\n']
If using Python 2.x it is recommended you use the raw_input() function and the input() function in Python 3.x. Like below
>>> raw_input()
test
'test'
Here's my python code. Could someone show me what's wrong with it.
while 1:
date=input("Example: March 21 | What is the date? ")
if date=="June 21":
sd="23.5° North Latitude"
if date=="March 21" | date=="September 21":
sd="0° Latitude"
if date=="December 21":
sd="23.5° South Latitude"
if sd:
print sd
And Here's what happens:
>>>
Example: March 21 | What is the date?
Traceback (most recent call last):
File "C:\Users\Daniel\Desktop\Solar Declination Calculater.py", line 2, in <module>
date=input("Example: March 21 | What is the date? ")
File "<string>", line 0
^
SyntaxError: unexpected EOF while parsing

Use raw_input instead of input :)
If you use input, then the data you
type is is interpreted as a Python
Expression which means that you
end up with gawd knows what type of
object in your target variable, and a
heck of a wide range of exceptions
that can be generated. So you should
NOT use input unless you're putting
something in for temporary testing, to
be used only by someone who knows a
bit about Python expressions.
raw_input always returns a string
because, heck, that's what you always
type in ... but then you can easily
convert it to the specific type you
want, and catch the specific
exceptions that may occur. Hopefully
with that explanation, it's a
no-brainer to know which you should
use.
Reference
Note: this is only for Python 2. For Python 3, raw_input() has become plain input() and the Python 2 input() has been removed.
Indent it! first. That would take care of your SyntaxError.
Apart from that there are couple of other problems in your program.
Use raw_input when you want accept string as an input. input takes only Python expressions and it does an eval on them.
You are using certain 8bit characters in your script like 0°. You might need to define the encoding at the top of your script using # -*- coding:latin-1 -*- line commonly called as coding-cookie.
Also, while doing str comparison, normalize the strings and compare. (people using lower() it) This helps in giving little flexibility with user input.
I also think that reading Python tutorial might helpful to you. :)
Sample Code
#-*- coding: latin1 -*-
while 1:
date=raw_input("Example: March 21 | What is the date? ")
if date.lower() == "march 21":
....
I had this error, because of a missing closing parenthesis on a line.
I started off having an issue with a line saying:
invalid syntax (<string>, line ...)?
at the end of my script.
I deleted that line, then got the EOF message.
While #simon's answer is most helpful in Python 2, raw_input is not present in Python 3. I'd suggest doing the following to make sure your code works equally well in Python 2 and Python 3:
First, pip install future:
$ pip install future
Second: import input from future.builtins
# my_file.py
from future.builtins import input
str_value = input('Type something in: ')
And for the specific example listed above:
# example.py
from future.builtins import input
my_date = input("Example: March 21 | What is the date? ")
I'm using the follow code to get Python 2 and 3 compatibility
if sys.version_info < (3, 0):
input = raw_input
I'm trying to answer in general, not related to this question, this error generally occurs when you break a syntax in half and forget the other half. Like in my case it was:
try :
....
since python was searching for a
except Exception as e:
....
but it encountered an EOF (End Of File), hence the error. See if you can find any incomplete syntax in your code.
i came across the same thing and i figured out what is the issue. When we use the method input, the response we should type should be in double quotes. Like in your line
date=input("Example: March 21 | What is the date? ")
You should type when prompted on console "12/12/2015" - note the " thing before and after. This way it will take that as a string and process it as expected. I am not sure if this is limitation of this input method - but it works this way.
Hope it helps
After the first if statement instead of typing "if" type "elif" and then it should work.
Ex.
` while 1:
date=input("Example: March 21 | What is the date? ")
if date=="June 21":
sd="23.5° North Latitude
elif date=="March 21" | date=="September 21":
sd="0° Latitude"
elif date=="December 21":
sd="23.5° South Latitude"
elif sd:
print sd `
What you can try is writing your code as normal for python using the normal input command. However the trick is to add at the beginning of you program the command input=raw_input.
Now all you have to do is disable (or enable) depending on if you're running in Python/IDLE or Terminal. You do this by simply adding '#' when needed.
Switched off for use in Python/IDLE
#input=raw_input
And of course switched on for use in terminal.
input=raw_input
I'm not sure if it will always work, but its a possible solution for simple programs or scripts.
Check the version of your Compiler.
if you are dealing with Python2 then use -
n= raw_input("Enter your Input: ")
if you are dealing with python3 use -
n= input("Enter your Input: ")
Check if all the parameters of functions are defined before they are called.
I faced this problem while practicing Kaggle.
