901 PointsHow do I solve it
I need to write a function named squared that takes a single argument.
If the argument can be converted into an integer, convert it and return the square of the number (num ** 2 or num * num).
If the argument cannot be turned into an integer, return the argument multiplied by its length. how can I convert a string to an integer
def squared(num):
try int(num):
return num*num
except ValueError:
return num*len(num)
# EXAMPLES
# squared(5) would return 25
# squared("2") would return 4
# squared("tim") would return "timtimtim"

will check if the conversion is possible but it doesn't retain the converted value. Either, update num
with assigned conversion:
try:
int = int(num)
return num * num
except....
Or convert in the `return statement:
try:
return int(num) * int(num)
except....
