Python 打印列表时以字母开始行？

Question

我希望我的代码打印为

a. [value1]
b. [value2]
c. [value3]
d. [value4]
e. [value5]
f. [value6]

我目前以

的形式设置了一个简单的计数器

counter = 0
for key in sorted(word_counter):
    counter+=1
    print(counter, key, word_counter[key])

Word_counter 用于我已经编写的另一个函数，它已经完成，我只是想修复它的打印方式。它目前在开头使用数字，但我希望它像第一个示例一样使用字母。

忘了补充，一旦它命中 z 我希望接下来的字母是 aa。 bb。像这样：

x. [value24]
y. [value25]
z. [value26]
aa. [value27]
bb. [value28]
cc. [value29]

字母表的每次迭代都会在末尾添加一个字母。

Answer 1

使用字符串包。

import string

list_of_alphabets = list(string.ascii_lowercase)

for i in range(your number(not greater than 26)): print list_of_alphabets[i] #your task of printing value

Answer 2

这很简单：

>>> import string
>>> from itertools import cycle
>>> x = range(100)
>>> letters = string.ascii_lowercase
>>> m = len(letters)
>>> for i, (let, e) in enumerate(zip(cycle(letters), x)):
...     print("{}. [{}]".format(let*(i//m+1), e))
...

Answer 3

import string

In [7]:     def letter(n):
   ...:         alphabet = string.ascii_lowercase
   ...:     
   ...:         count = 0 
   ...:         while count < n:
   ...:             iteration = (int(count / 26.) + 1)
   ...:             letter = alphabet[count % 26]
   ...:             yield letter * iteration
   ...:             count += 1
   ...:     
   ...:     print '\n'.join(['{0} value{1}'.format(l, i) for i, l in enumerate(letter(100))])

a value0
b value1
c value2
d value3
e value4
f value5
g value6
...
dd value29
ee value30
ff value31
gg value32
hh value33
ii value34
jj value35
