python txt文本处理

对于Python中的文本处理，可以使用内置的文件操作功能和字符串方法来处理txt文本文件。以下是一些常见的文本处理任务及其对应的Python代码示例：

1. 读取文本文件：

with open('file.txt', 'r') as file:
    content = file.read()

2. 写入文本文件：

content = "Hello, World!"
with open('file.txt', 'w') as file:
    file.write(content)

3. 逐行读取文本文件：

with open('file.txt', 'r') as file:
    lines = file.readlines()
    for line in lines:
        print(line)

4. 搜索特定字符串：

content = "Hello, World!"
if "World" in content:
    print("Found")
else:
    print("Not Found")

5. 替换字符串：

content = "Hello, World!"
new_content = content.replace("Hello", "Hi")
print(new_content)

6. 分割字符串：

content = "Hello, World!"
words = content.split()
print(words)

7. 统计单词数量：

content = "Hello, World!"
words = content.split()
word_count = len(words)
print(word_count)

8. 统计特定词出现次数：

content = "Hello, World! Hello, Universe!"
word_to_count = "Hello"
count = content.count(word_to_count)
print(count)
