最新学习python使用到的替换文件文本的操作。
# 传入文件(file),将旧内容(old_content)替换为新内容(new_content)
def replace(file, old_content, new_content):
content = read_file(file)
content = content.replace(old_content, new_content)
rewrite_file(file, content)
# 读文件内容
def read_file(file):
with open(file, encoding='UTF-8') as f:
read_all = f.read()
f.close()
return read_all
# 写内容到文件
def rewrite_file(file, data):
with open(file, 'w', encoding='UTF-8') as f:
f.write(data)
f.close()
# 替换操作(将test.txt文件中的'Hello World!'替换为'Hello Qt!')
replace(r'test.txt', 'Hello World!', 'Hello Qt!')
