如何从文本中删除空格、标点符号和符号

import re

def remove_punctuation(text):
    # 匹配空格、标点符号和符号
    pattern = r"[^\w\s]"
    # 使用空字符替换匹配到的字符
    processed_text = re.sub(pattern, "", text)
    return processed_text

# 示例用法
text = "Hello, World! This is a sample text."
processed_text = remove_punctuation(text)
print(processed_text)  # 输出：Hello World This is a sample text

def remove_punctuation(text):
    punctuation = ".,?!;:'\"[]{}()<>@#$%^&*_+-=\\|~`"
    for char in punctuation:
        text = text.replace(char, "")
    return text

# 示例用法
text = "Hello, World! This is a sample text."
processed_text = remove_punctuation(text)
print(processed_text)  # 输出：Hello World This is a sample text

def remove_punctuation(text):
    punctuation = " .,?!;:'\"[]{}()<>@#$%^&*_+-=\\|~`"
    words = text.split()
    processed_text = " ".join(word for word in words if word not in punctuation)
    return processed_text

# 示例用法
text = "Hello, World! This is a sample text."
processed_text = remove_punctuation(text)
print(processed_text)  # 输出：Hello World This is a sample text
