>>> import string
>>> string.ascii_lowercase[:14]
'abcdefghijklmn'
>>> string.ascii_lowercase[:14:2]
'acegikm'
要做网址,你可以使用类似的东西
[i + j for i, j in zip(list_of_urls, string.ascii_lowercase[:14])]

假设这是一个家庭作业;-) - 不需要召唤库等 - 它可能希望你使用chr / ord的range(),如下所示:
for i in range(ord('a'), ord('n')+1):
print chr(i),
对于其余部分,只需使用范围()

提示:
import string
print string.ascii_lowercase
和
for i in xrange(0, 10, 2):
print i
和
"hello{0}, world!".format('z')

small_letters = map(chr, range(ord('a'), ord('z')+1))
big_letters = map(chr, range(ord('A'), ord('Z')+1))
digits = map(chr, range(ord('0'), ord('9')+1))
或
import string
string.letters
string.uppercase
string.digits
此解决方案使用ASCII table。 ord
获取字符的ascii值,chr
反之亦然。
>>> small_letters = map(chr, range(ord('a'), ord('z')+1))
>>> an = small_letters[0:(ord('n')-ord('a')+1)]
>>> print(" ".join(an))
a b c d e f g h i j k l m n
>>> print(" ".join(small_letters[0::2]))
a c e g i k m o q s u w y
>>> s = small_letters[0:(ord('n')-ord('a')+1):2]
>>> print(" ".join(s))
a c e g i k m
>>> urls = ["hello.com/", "hej.com/", "hallo.com/"]
>>> print([x + y for x, y in zip(urls, an)])
['hello.com/a', 'hej.com/b', 'hallo.com/c']

这个问题的答案很简单,只需制作一个名为ABC的列表:
ABC = ['abcdefghijklmnopqrstuvwxyz']
每当你需要引用它时,只需:
print ABC[0:9] #prints abcdefghij
print ABC #prints abcdefghijklmnopqrstuvwxyz
for x in range(0,25):
if x % 2 == 0:
print ABC[x] #prints acegikmoqsuwy (all odd numbered letters)
也试试这打破你的设备:D
##Try this and call it AlphabetSoup.py:
ABC = ['abcdefghijklmnopqrstuvwxyz']
try:
while True:
for a in ABC:
for b in ABC:
for c in ABC:
for d in ABC:
for e in ABC:
for f in ABC:
print a, b, c, d, e, f, ' ',
except KeyboardInterrupt:
pass
