Question

Is there a way to pass a variable to the choice() function for a list. I have a bunch of lists and I want to randomly select from one list and then use the string that is returned to select from a list that has that string name.

A = ['1','2','3']

print choice (A) - this gets me a random choice from the list

but I want to to store the choice as a variable and use it to call another list

A = ['1','2','3']
1 = ['A','B','C']

Var1 = choice (A)

print choice (Var1) *** this is my problem, how do I pass a variable to the choice function

Thanks for the help!

Answer 1

In Python, you can do this using references.

A = [1, 2, 3]
B = [4, 5, 6]
C = [7, 8, 9]
MasterList = [A, B, C]

whichList = choice(MasterList)
print choice(whichList)

Note that A, B, C are names of previously assigned variables, instead of quoted strings. If you ever find yourself using quoted names to refer to variables, there’s usually a better way to do whatever you’re trying to do.
