"print" throws an invalid syntax error in Python 3
(4 answers)
Closed 2 years ago.
This is for Python 2:
import re
print sum([int(i) for i in re.findall('[0-9]+',open(raw_input('What is the file you want to analyze?\n'),'r').read())])
But why do I get a syntax error with Python 3?
Python3
import re
print sum([int(i) for i in re.findall('[0-9]+',open(input('What is the file you want to analyze?\n')).read())])
That is because in Python3 you should use brackets around the argument for the print function.
print()
so your code will work as soon as you write
print(sum([int(i) for i in re.findall('[0-9]+',open(input('What is the file you want to analyze?\n')).read())]))

it seems like that you have copied code from an interpreter or a book to a file and tried to run it with python command.
if you want to do so you need to remove >>> from lines and run again.

Why am I getting this error (see linting) saying 'End of statement expected' in pycharm?
I am very new to python.
Try print with parenthesis in Python3 i.e. print(x) instead of print x

You are using Python 3, In this version print is not a keyword it is a function.
Try this :
print("hello")

Syntax error on print with Python 3 [duplicate]

def creating_table():
mailingTable = open("mailingTable.txt", "r")
lines = mailingTable.readline()
for line in lines:
print line
mailingTable.close()
It says print line is invalid syntax. Why? I m using python 3.3.5
In Python 3.x, you have to write print() as follows, because now it's a function:
print(line)
In Python 2.x it was possible to omit the (), but that's no longer the case.

I'm getting the following error:
File "foo.py", line 6
print "This implementation requires the numpy module."
^
SyntaxError: invalid syntax
In this Python code:
#!/usr/bin/python
try:
import numpy
except:
print "This implementation requires the numpy module."
exit(0)

if __name__ == "__main__":
R = [

What is wrong?
EDIT: I use Python 3.3
This should be:
print("....")
Starting with python 3, print is a function, not a special case statement.
