Getting the first x item from a list

Good Primer for Python Slice Notation

I have a string and I'm splitting in a ; character, I would like to associate this string with variables, but for me just the first x strings is useful, the other is redundant;

I wanted to use this code below, but if there is more than 4 coma than this raise an exception. Is there any simply way?

az1, el1, az2, el2, rfsspe = data_point.split(";")

Yes! Use slicing:

az1, el1, az2, el2, rfsspe = data_point.split(";")[:5]

That "slices" the list to get the first 5 elements only.

方式，我这样做通常是将所有变量添加到列表（var_list），然后当我处理列表时，我做了类似

for x in var_list[:5]:
    print x #or do something
