Python中使用letter()函数生成随机字母序列并计算其出现频率的方法

Python中可以使用random模块的choices()函数来生成随机字母序列，然后使用collections模块的Counter类来计算每个字母的出现频率。

下面是一个生成随机字母序列并计算出现频率的例子：

import random
from collections import Counter

def generate_random_letters(length):
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    random_letters = ''.join(random.choices(alphabet, k=length))
    return random_letters

def calculate_letter_frequency(random_letters):
    letter_counter = Counter(random_letters)
    frequency = {letter: count/len(random_letters) for letter, count in letter_counter.items()}
    return frequency

length = 1000
random_letters = generate_random_letters(length)
frequency = calculate_letter_frequency(random_letters)

print("随机字母序列:", random_letters)
print("字母频率:")
for letter, freq in frequency.items():
    print(f"{letter}: {freq:.2%}")

运行该代码，会生成一个长度为1000的随机字母序列，并计算每个字母的出现频率。输出示例：
