Why do I get an invalid syntax when defining a global variable?

问题

def pLatin_converter (self):
    movetoend = ""
    index = 0
    global pig = ""

I'm getting an 'invalid syntax' on the global pig = "" line and I don't understand why.

回答1:

The global variable can't be assigned a value in the global statement.

Split the two:

global pig
pig=""
