一次从每个列表中返回 1 项

Question

I have two lists:

chars = 'abcdefghijklmnopqrstuvwxyz'
columns = ['item', 'desc', 'price', 'currency', 'country', 'state', 'postcode']

Basically, I want it to print:

a item
b desc
c price
etc...

I tried doing:

for i in range(0, len(columns)):
    for char in chars:
        print(char, columns[i])

But that prints each letter with column[i]

Answer 1

You can use zip for this:

for char, col in zip(chars, columns):
    print(char, col)

Answer 2

Use zip(), iterate then print.

zipped = zip(chars, columns)

for item in zipped:
    print(item[0], item[1])

Answer 3

Just a way without an explicit alphabet (which is always error-prone and I've seen many people forget letters):

for i, col in enumerate(columns, start=ord('a')):
    print(chr(i), col)
