How can you count the number of letters in a word using Python?

To count the number of letters in a word, you can use string methods in Python to handle it. Below is an example code demonstrating how to count the number of letters in a word.

word = input("请输入一个单词：")  # 获取用户输入的单词

# 使用字符串的 isalpha() 方法来判断字符是否为字母，并通过循环统计字母的个数
letter_count = 0
for char in word:
    if char.isalpha():
        letter_count += 1

print("单词中字母的个数为:", letter_count)

This code first uses the input() function to get a word input from the user, then uses a for loop to iterate through each character in the word. During the loop, it uses the isalpha() method to check if the character is a letter, if it is, the letter counter letter_count is incremented by 1. Finally, the code outputs the number of letters.
