如何使用python从字符串中弹出任何字符？

def pop_char(s, index):
    if index < 0 or index >= len(s):
        raise IndexError("Index out of range")
    return s[:index] + s[index+1:]

# 示例用法
original_string = "Hello, World!"
index_to_pop = 5
new_string = pop_char(original_string, index_to_pop)
print(new_string)  # 输出: "Helo, World!"

def pop_last_char(s):
    if not s:
        raise ValueError("String is empty")
    return s[:-1], s[-1]

# 示例用法
original_string = "Hello, World!"
new_string, popped_char = pop_last_char(original_string)
print(new_string)  # 输出: "Hello, World"
print(popped_char)  # 输出: "!"
