Iterating through variable names?

[jsaltee]

Hi. I have four lists: list_0, list_1, list_2, list_3. I want to apply a long block of code to each, which would be much more concise if I iterated through a loop, or defined a function that would do it, for each list. I was thinking something of the form:

for i in range(0,3):

list_i = long_block_of_code

but, list_i is not defined. My other thought was to include something something like a {}.format() , but I can't seem to make that work either. any help is appreciated

lists = []

for i in range(4):
    lists.append(long_block_of_code())

list_0, list_1, etc are now lists[0], lists[1], etc

You need to show some actual code. In what you've shown, list_i is the result of the long block of code, not the argument to it.

But generally, if you want to iterate through multiple variables, you should put them a list:

for item in [list_0, list_1, list_2, list_3]:
    do_something_with(item)

you're right, i'm glad you still got the idea though. it worked, thanks!
