write a program which prints the day in english

[snippsat]

I guess with my code its impossible to do it, I have to use a new code for it? i mean, restart it.

No you just need to add the user input to what Yoriz has showed you.
I would add a function like to make cleaner,and the point is that no if,elif is needed for this.

import calendar

def day_of_week(year, month, day):
    weekday = calendar.weekday(year, month, day)
    print(f"Day of the week in english is {calendar.day_name[weekday]}")

if __name__ == '__main__':
    year = int(input("Please choose your year: "))
    month = int(input("Please choose your month: "))
    day = int(input("Please choose your day: "))
    day_of_week(year, month, day)

Test.

Output:
Please choose your year: 2021
Please choose your month: 7
Please choose your day: 24
Day of the week in english is Saturday
