Python Python Basics (Retired) Things That Count Things That Count

I can't figure out how to multiply int

The challenge is to create a variable for age and a second variable for days where it multiplies the age by 52 and by 7.

This is what I have-

age = int(27)

days: print(int('age')*int(52)*int(7))

days_alive.py 
age = int(27)

days:
  print(int('age')*int(52)*int(7))

In Python, you aren't required to declare the variable type, as it is not a statically typed language. Python will figure out that:

age = 25

Means that you want to assign the integer 25 to the variable age.

With that in mind, all the question is asking you is the following:

days = age * 52 * 7

I hope that helps clarify the way Python handles variables!

On a side-note, if you ever want to find out what type your variable is, try the following:

type(age)

Will return:

<type 'int'>

This is awesome thank you! I think I was overcomplicating it unnecessarily.

[age] field should not be in quotes. Also, Not familiar with colon (:) syntax after 'days', I would calc "days = int(age), etc'' then "print(days)".

age is already int age = int(27) print(age*int(52)*int(7)) print(int(27)*int(52)*int(7)) print("{}".format(age*int(52)*int(7)))

Mustafa, so would the string

print("{}".format(age*int(52)*int(7)))

be the best one?
