Python indent Difference Analysis

The following two python programs have the same code but different running results, because the last line of return indentation is different.
Copy codeThe Code is as follows:
Def powersum (power, * args ):

'''Return the sum of each argument raised to specified power .'''
Total = 0
For I in args:
Total + = pow (I, power)
Return total

Input powersum (2, 3, 4) at runtime output 25 (3 square plus 4 square)
Copy codeThe Code is as follows:
Def powersum (power, * args ):
'''Return the sum of each argument raised to specified power .'''
Total = 0
For I in args:
Total + = pow (I, power)
Return total

Input powersum (2, 3, 4) at runtime to output 9 (3 square)

It can be seen that you cannot indent code written in python at will.
