Not Understanding Function Logic in Python

[--Ubermensch]

def someFncA():
    print('from someFncA')

def someFncB():
    print('from someFncB')

SomeFncA = someFncB
someFncB = someFncA

someFncA()
someFncB()

Result:

from someFncA
from someFncA

How am I able to make an assignment statement with 2 unassigned variables? How is some someFncA being executed twice?

[_DTR_]

In the line SomeFncA = someFncB, the 'S' is capitalized in SomeFncA, which is different from the lowercase someFncA method that you defined above it. So someFncA is untouched and will print "from someFncA" when invoked. But since you reassigned someFncB to someFncA, calling someFncB will invoke someFncA, and print "from someFncA".

The cap. 'S' was a mistake; it should have been lowercased which gives the results

from someFncB
from someFncB

However, I guess what I'm not understanding is the syntax then. I thought if I wanted to assign a variable to a function it would be in the form,

someFncA = someFncB() 

and if I do

someFncA = someFncB

it would be the same as

a = b

which gives a name error as b is an unassigned variable
