This “underscoring” seems to occur a lot, and I was wondering if this was a requirement in the Python language, or merely a matter of convention?
I’d like to pass a math operator, along with the numeric values to compare, to a function. Here is my broken code:
Let’s take a simple code: y = [1,2,3] def plusOne(y): for x in range(len(y)): y[x] += 1 return y print plusOne(y), y a = 2 def plusOne2(a): a += 1 return a print plusOne2(a), a Values of ‘y’ change but value ‘a’ stays the same. I have already learned that it’s because one is mutable … Read more
