# EXAMPLES
# squared(5) would return 25
def squared(arg1):
    try: #try not Try
        intarg1 = int(arg1)
#        continue
    except:
        return arg1 * len(arg1)
        break
    return arg1 * arg1 # arg1 **2   
# squared("2") would return 4
# squared("tim") would return "timtimtim"

if arg1 is not integer and you want to do:

intarg1 = int(arg1)

this program will give ValueError, so needs for python:

except ValueError:

and you do not need break in this function because there is no loop

        except:
                return arg1 * len(arg1)
                break

and last mistake, if your arg1 is number but its data type string, you need to return square of int(arg1)

        except:
                return arg1 * len(arg1)
                break
        return intarg1 * intarg1

Note: pay attention for spaces before write statements

try:
    #your code
except ValueError:
    try:
        #another code
    except KeyError:
        try:

    #blah blah blah :)

if you learn more detail about try except, check other sites and see.

Thanks Ismail. Which are the "write statements" -pay attention for spaces before write statements?

Answer worked if except: as i am catching all errors not only ValueError.

Because spaces determine how your command will be independent for ex:

for i in range(0,15)                        #loop 1 -----> No spaces
    for j in range (1,5)                    #loop 2 -----> 4 spaces
        for t in range (0 ,8)               #loop 3 -----> 8 spaces
  • loop 3 in loop 2 (loop 3 not independent of loop 2)
  • loop2 in loop 1 (loop 2 not independent of loop 1)
