So I'm not sure how to describe this or google it. What i want is to use a variable to access another variable. I'm guessing the answer will be using a dictionary of sorts.
personPaul = [1,2]
personJoe = [3,4]
def myFunc(name):
return person + name
print myFunc("Paul")
print myFunc("Joe")
I want the output to be
[1,2]
[3,4]

Exactly right :-)
people = {
"Paul": [1,2],
"Joe": [3,4]
}
def myFunc(name):
return people[name]
print myFunc("Paul")
print myFunc("Joe")
Of course, you can also cut out the myFunc middleman and directly do print people["Paul"].
myFunc = people.get.Is this what you are after?:
people = {
"Paul":[1,2],
"Joe":[3,4]
}
print people["Paul"] # Gives you [1,2]
print people["Joe"] # Gives you [3,4]
You can use globals() function to access to global variables inside the function and then use a generator expression within next function to loop over its items then check if your name is in a global name (the key) then print its corresponding value :
>>> personPaul = [1,2]
>>> personJoe = [3,4]
>>> def myFunc(name):
... return next((v for k,v in globals().items() if name in k),None)
...
>>> myFunc('Paul')
[1, 2]
>>> myFunc('jack')
>>>
globals().get(name, None).
