使用内置的范围函数打印python中的大写字母和小写字母

def upperCaseAlphabets():
    print("Upper Case Alphabets")
    for i in range(65, 91):
        print(chr(i), end=" ")
    print()

def lowerCaseAlphabets():
    print("Lower Case Alphabets")
    for i in range(97, 123):
        print(chr(i), end=" ")

upperCaseAlphabets();
lowerCaseAlphabets();

如果你正在寻找R中[1:10]的等价字母，你可以使用:

import string
list(string.ascii_lowercase[0:10])

下面是一个简单的字母范围实现:

Code

def letter_range(start, stop="{", step=1):
    """Yield a range of lowercase letters.""" 
    for ord_ in range(ord(start.lower()), ord(stop.lower()), step):
        yield chr(ord_)

Demo

list(letter_range("a", "f"))
# ['a', 'b', 'c', 'd', 'e']

list(letter_range("a", "f", step=2))
# ['a', 'c', 'e']

下面是我如何基于string.ascii_letters实现字母范围生成的自定义函数:

from string import ascii_letters


def range_alpha(start_letter, end_letter):
  return ascii_letters[
    ascii_letters.index(start_letter):ascii_letters.index(end_letter) + 1
  ]

print(range_alpha('a', 'z'))
print(range_alpha('A', 'Z'))
print(range_alpha('a', 'Z'))

[chr(i) for i in range(ord('a'),ord('z')+1)]
