I am trying to get the difference in between two dates using Python. But every time I run my code I get time mentioned in my result that is [00:00:00]. How do we remove and just display number of days.
import datetime
now = datetime.datetime.today().date()
print(now)
userinput = input('Enter your deadline of the project(mm/dd/yyyy)')
projectdate = datetime.datetime.strptime(userinput,'%m/%d/%Y').date()
print(projectdate)
daysleft = projectdate - now
result = (projectdate - now).days//7
print('The number of days left in your project are....' +' '+ str(daysleft) + ' '+ 'days' + ' ' + 'or' + ' ' + str(result) +' ' + 'weeks')
change
str(daysleft)
to
str(daysleft.days)
For your use case (you only care about time entities bigger than an hour) - you might want to use datetime.date rather than datetime.datetime.
Datetime module has special class called datetime.timedelta that represents a time interval and can be easily converted. E.g.
start = datetime.date(year=2019, month=3, day=1)
finish = datetime.date(year=2019, month=5, day=1)
print("There are " + str((finish - start).days) + " days between start and finish")
You can also make slight modification to the print statement
print('The number of days left in your project are....' +' '+ str(daysleft.days) + ' '+ 'days' + ' ' + 'or' + ' ' + str(result) +' ' + 'weeks')

I'm doing one of my first assignments and I can't find out how to put parentheses around a variable when I go to print it.
I've tried
(xs)
{xs}
[xs}
But none get parentheses around it
(print)("Hello user! Welcome to the program!")
name = input("What is your name?")
(print)("Hello", name)
x = input("What is your favorite number?")
y = int(x) // 2
xs = str(x)
ys = str(y)
z = ("Did you know that half of your favorite number" + ' ' + xs + ' ' + 'is' + ' ' + ys + '?')
print(z)
For the 2nd to last line of code I want it to say Did you know that half of your number (5) is 2?
5 is just an example number but I want it in parentheses!
Do it like so:
z = ("Did you know that half of your favorite number" + ' (' + xs + ') ' + 'is' + ' ' + ys + '?')
you just need to add the pharentesis in the right place, something like this:
z = ("Did you know that half of your favorite number" + ' (' + xs + ') ' + 'is' + ' ' + ys + '?')
I am not exactly sure if that is what you need but you just have to concat "(" and ")" around your variable.
>>> y = "number"
>>> print ( "(" + y + ")" )
(number)
Am trying to write a function to print numbers in steps.Here is my code
def steps(num):
v = num
for i in range(1, v+1):
print(" "*i + str(i)*3)
print(steps(3))
The result appears as
111
222
333
None
I am trying to get rid of the "none" word any help? Note please, i don't want to get rid of the print statement in "print(steps(3)), any other method or solution will be welcomed.
You need to output the spaces yourself like so:
for i in range(1, v + 1):
print(" " * i + str(i) * 3)
def steps(number):
mystr = ""
for i in range(1, number + 1):
mystr += 3*str(i) + '\n' + i*'\t'
return mystr
I am only three weeks into my Intro to Programming course, so bear with me!
I am writing a code as follows:
number1 = input('Enter the first number: ')
number1 = int(number1)
number2 = input('Enter the second number: ')
number2 = int(number2)
number3 = input('Enter the third number: ')
number3 = int(number3)
ratio12 = int(number1 / number2)
ratio13 = int(number1 / number3)
ratio23 = int(number2 / number3)
print('The ratio of', + number1, '+', + number2,'is', + ratio12, '.')
print('The ratio of', + number1, '+', + number3,'is', + ratio13, '.')
print('The ratio of', + number2, '+', + number3,'is', + ratio23, '.')
The code is functional (finally), but I can't seem to get rid of the space before the period on the print statements. Is there a way that I can do that?
The reason why this happens is because you are using commas in your print statements. In python there are a few ways to give the print statement multiple variables, you seem to be mixing two of them together. The ways are as follows.
Concatenate the string.
print('The ratio of ' + str(number1) + ' + ' + str(number2) + ' is ' + str(ration12) + '.')
This way is probably the most basic way. It will join the strings without adding any characters in between them (e.g. no spaces in between unless you add them explicitly.) Also note, that string concatenation won't automatically cast the integers to a string for you.
Pass print multiple arguments.
print('The ratio of', number1, '+', number2, 'is', ration12, '.')
This will automatically add spaces between each argument and is what is happening in your case. The separator (which defaults to a space) can be changed by passing a keyword argument to the print function. For example, print('i = ', i, sep='')
Use string formatting.
print('The ratio of {} + {} is {}.'.format(number1, number2, ratio12))
This way is the most readable and often the best way. It will replace the '{}' sections in you 'template' string with the arguments based into the format function. It does this in order, however you can add an index like this '{0}' to explicitly use an argument by index.
Some string formating makes your live easier:
number1 = 1
number2 = 2
ratio12 = number1 / number2
print('The ratio of {} + {} is {}.'.format(number1, number2, ratio12))
Output:
The ratio of 1 + 2 is 0.5.
You can control the "separator" using the sep argument to print:
print('The ratio of', + number1, '+', + number2,'is', + ratio12, '.', sep='')
Note that this will change the spacing between the other items as well.
Also -- You don't need the extra + operators in there. Here's a version without the spaces and with explicit spaces added where I think you want them:
print('The ratio of ', number1, ' + ', number2, ' is ', ratio12, '.', sep='')
You're confused about the concatenation function and print fields. If you're going to concatenate all those strings, just use concatenation. The comma includes the default separator.
print('The ratio of', number1, '+', number2,'is', str(ratio12) + '.')
Try to write to it this way:
print('The ratio of %d + %d is %d.' %(number1, number2, ratio12))
print('The ratio of %d + %d is %d.' %(number1, number3, ratio13))
print('The ratio of %d + %d is %d.' %(number2, number3, ratio23))
That's the way print works when you give it multiple comma separated arguments. The logic behind that is that when you quickly want to print a bunch of variables, it's a pain to manually add widespace.
Well, one thing to try: Get rid of all the , in the print statement. You can just chain strings using the + sign.
So,
print('The ratio of ' + str(number1) + ' ' + str(number2) + ' is ' + str(ratio12) + '.')
If you need even greater control over formatting, you'd want to look into the format function.
print("The ratio of {} + {} is {}.".format(number1, number2, ratio12))
I am trying to do a simple toto history with a dictionary and function however I have this funny syntax error that keeps appearing that states "unexpected EOF while parsing" on the python shell when I try to runs it. I re-looked over and over however I cannot find the error. I used input for input of integers therefore I do not think that the problem might lie with the input or raw_input. Please help me ! Below are my codes and the error on the python shell.
options()
choice = input ("Enter your choice: ")
print
while choice != -1:
if choice == 1:
print("Choice 1")
for key in toto_book:
print key + "\t" + "Day: " + toto_book[key][0] + '\t' + 'Winning Numbers: ' + str(toto_book[key][1] + 'Additional Number: ' + toto_book[key][2]
elif choice == 2:
print("Choice 2")
draw = raw_input("Enter draw date(dd/mm/yy): ")
if draw in toto_book:
print (draw + "\t" + "Day: " + toto_book[draw][0] + "\t" + "Winning Numbers: " + str(toto_book[draw][1]) + 'Additional Number: ' + toto_book[draw][2])
else:
print draw + ' cannot be found.'
There is a syntax error at the elif choice == 2: line.

As pointed out by #cricket_007, this answer is based on the false assumption that Python 3 is being used. Actually, Python 2 is being used and the only serious problem is that the call to str is missing a closing parenthesis.
You are using Python 3 in which print is a function, not a statement (as it is in Python 2).
This is the line causing the problem:
print key + "\t" + "Day: " + toto_book[key][0] + '\t' + 'Winning Numbers: ' + str(toto_book[key][1] + 'Additional Number: ' + toto_book[key][2]
Add parentheses to make print a function call, i.e. print(...):
print(key + "\t" + "Day: " + toto_book[key][0] + '\t' + 'Winning Numbers: ' + str(toto_book[key][1]) + 'Additional Number: ' + toto_book[key][2])
Also, the call to str() was missing the closing parenthesis.
There is a similar problem on line 15.
Other problems:
input() returns a string, not an integer so your if choice ==
statements will never be true. Either convert choice to an integer
with choice = int(choice) after the input(), or use a string in
the if statements, e.g. if choice == '1'.
The while loop is infinte, and unnecessary for the code shown (perhaps it is a work in progress?).
