用Python替换文本文件中的占位符可以通过以下步骤实现:
with open('file.txt', 'r') as file:
content = file.read()
{{placeholder}}
,要替换为replacement
:content = content.replace('{{placeholder}}', 'replacement')
with open('file.txt', 'w') as file:
file.write(content)
完整的Python代码示例:
with open('file.txt', 'r') as file:
content = file.read()
content = content.replace('{{placeholder}}', 'replacement')
with open('file.txt', 'w') as file:
file.write(content)
这样,文本文件中的占位符就会被替换为指定的内容。请注意,这只是一个简单的示例,实际应用中可能需要更复杂的替换逻辑。
