2,465 PointsPython defining a function
Hi, I've been revising by writing 'very basic' definition of functions, and its hit and miss most of the time with SyntaxError appearing. some codes I write don't have this, and some of them are identical. I can't seem to figure out what I am doing wrong. any help appreciated Thanks
def future_age(age): old = age + 10 print ("in ten years, you will be" , old , "years old")
take_age = int(input("what is your age? ") future_age(take_age)
File "play.py", line 6
future_age(take_age)
^
SyntaxError: invalid syntax

take_age = int(input("what is your age? ") # <-- missing ) symbol
And when posting code in future, use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area.
