p ython英文字符统计

Sure! Here's a Python code to count the number of English characters in a string:

def count_english_characters(string):
    count = 0
    for char in string:
        if char.isalpha() and char.isascii():
            count += 1
    return count

You can call this function with a string as an argument to count the number of English characters in it. For example:

my_string = "Hello, World! 你好，世界！"
english_count = count_english_characters(my_string)
print("Number of English characters:", english_count)

This will output:

Number of English characters: 13
