passing parameters to a funcion: do I need to use an alias?

Question

Can I use the same var name when passing a value to a function in Python, like this?:

def function(i):
    z=i+1
    print (z)

for i in range (0,100):
    function(i)

Or should I do it like this:

def function(x):
    z=x+1
    print (z)

for i in range (0,100):
    function(i)

what is the best practice?

The scopes are different, so you can use the same names in this context — rafaelc, Jul 23 '18 at 12:51
Both snippets should work, and the best practice is probably to name your variables in respect of their content and purpose. — T.Nel, Jul 23 '18 at 12:51

There's no technical reason why you should't use it, yet I'd strongly suggest to get rid of habit of naming variables like i or f or so, instead of number_of_beds_in_reserved_room (or camelCase if you prefer so :). By keeping bad habits with short variable names you save nothing nowadays, yet risk a lot of stepping of variable name shadowing which may be pretty damn hard to debug. RAM is cheap. Your time is not.
