I'm unable to get date with a variable

def get_next_monday(year, month, day):
    date0 = datetime.date(year, month, day)
    next_monday = date0 + datetime.timedelta(7 - date0.weekday() or 7)
    return next_monday

date2 = datetime.datetime.now().strftime("%Y, %m, %d")
findnextweek = get_next_monday(date2)

If I replace (year, month, day) with (date2) I get Integer required. Otherwise, I get a different error

TypeError: get_next_monday() takes exactly 3 arguments (1 given)

You have some little problems in your code. Here's the fix and explanation:

import datetime

def get_next_monday(year, month, day):

    # if you want to accept str and int, you must convert the strings

    date0 = datetime.date(int(year), int(month), int(day))
    next_monday = date0 + datetime.timedelta(7 - date0.weekday() or 7)
    return next_monday


# you must convert the date in a list, because `get_next_monday` takes 3 arguments.
initial_date = datetime.datetime.now().strftime("%Y, %m, %d").split(',')

# you must un-pack the date
findnextweek = get_next_monday(*initial_date)

print(findnextweek)

Note that normally you should be calling get_next_monday with something like get_next_monday(2016, 6, 10) or get_next_monday('2016', '6', '10').

There's no much sense of creating datetime object, converting it in to an string, then a list, and finally re-converting in to a datetime object.

Anyways I hope it help you :)

You are passing a string value to your get_next_monday function but it is expecting 3 arguments.

date2 = datetime.datetime.now().strftime("%Y, %m, %d")

This will return a string similar to this: '2016, 06, 28'. You'll want to split that string into 3 variables in order to pass it to your function.

There are many ways to do this but I'll provide a super simple option:

year, month, day = date2.split(',')

This will populate year with "2016", month with " 06" and day with " 28". You can then pass these three variables to your get_next_monday function. Don't forget to convert the arguments to numbers before passing them to the date function: 

datetime.date( int(year), int(month), int(day) )

As you can see, the split function takes a string as an input and "breaks" the string up into parts. It will "break" the string every time it sees a "," character because that is the argument we are passing to the split function. In our example, the strings will still include some spaces - you could use strip() to remove them, or you could change the date format to not have spaces: strftime("%Y,%m,%d").
