编写一个函数接收一个字符串，返回输入字符串中的大写字母、小写字母和 数字的个数。

def count_chars(string):
    upper_count = 0
    lower_count = 0
    digit_count = 0
    other_count = 0
    for char in string:
        if char.isupper():
            upper_count += 1
        elif char.islower():
            lower_count += 1
        elif char.isdigit():
            digit_count += 1
        else:
            other_count += 1
    return (upper_count, lower_count, digit_count, other_count)

python编写一个函数接收一个字符串， 返回输入字符串中的大写字母、小写字母和 数字的个数

可以使用Python内置函数isupper()、islower()、isdigit()来判断字符的类型，然后统计个数即可。具体实现如下：

def count_chars(s):
upper_count =
lower_count =
digit_count =
other_count =
for c in s:
if c.isupper():
upper_count += 1
elif c.islower():
lower_count += 1
elif c.isdigit():
digit_count += 1
else:
other_count += 1
return (upper_count, lower_count, digit_count, other_count)

# 测试
s = "Hello, World! 123"
print(count_chars(s)) # 输出：(2, 8, 3, 4)

编写函数接收一个字符串分别统计大写字母小写字母数字其他字符的个数

以下是Python语言的代码实现：

def count_chars(s):
    upper_count = 0
    lower_count = 0
    digit_count = 0
    other_count = 0
    for c in s:
        if c.isupper():
            upper_count += 1
        elif c.islower():
            lower_count += 1
        elif c.isdigit():
            digit_count += 1
        else:
            other_count += 1
    return upper_count, lower_count, digit_count, other_count

该函数接收一个字符串作为参数，使用循环遍历字符串中的每个字符，根据字符的类型增加相应的计数器。最后返回各种字符的数量。可以使用多重赋值来获取返回值中的各项数量：

s = "Hello, World! 123"
upper_count, lower_count, digit_count, other_count = count_chars(s)
print("Upper case count:", upper_count)
print("Lower case count:", lower_count)
print("Digit count:", digit_count)
print("Other count:", other_count)

输出如下：

Upper case count: 2
Lower case count: 8
Digit count: 3
Other count: 3
