elif vs. if

[DeaD_EyE]

It depends what you want to do.
Here we have two independent if-blocks:

def foo(text, upper, strip):
    if upper:
        text = text.upper()
    if strip:
        text = text.strip()
    return text


foo('   Hello World   ', True, True)

But writing this with elif gives different results.

def foo(text, upper, strip):
    if upper:
        text = text.upper()
    elif strip:
        text = text.strip()
    return text


foo('   Hello World   ', True, True)

In this case upper is also True and the code-block is executed.
The second block after elif is not executed, because the first condition was true.
So only one if/elif/else-block is executed.
