Question

I wanted to calculate the median I don’t know what is wrong here
UPDATE:

def median(a,b,c):
    if a>b:
        if b>c:
        return b
        else:
        if a>c:
            return c
        else:
            return a
    else:
        if b<c:
            return b
        else:
        if a>c:
            return a
        else: 
            return c

My error is : File “prog.py”, line 4
return b
^
IndentationError: expected an indented block

Answer 1

Your indentation is wrong. Each else: must line up with its corresponding if ...:, and each nested block must be indented.

For example,

        if a>c:
            return c
                else:
                    return a

should read

        if a>c:
            return c
        else:
            return a

Code that isn’t indented correctly isn’t valid Python.

P.S. The entire function can be rewritten as follows:

def median(a, b, c):
    return sorted((a, b, c))[1]
