python中open写入文件自动换行
时间: 2023-10-27 08:59:44 浏览: 190
在Python中,使用open函数写入文件时,默认情况下是不会自动换行的。当你调用write方法写入内容时,如果你没有明确指定添加换行符"\n",那么写入的内容将会连续显示在同一行上。
例如,使用以下代码来打开一个文件并写入内容:
```python
with open("file.txt", "w") as file:
file.write("Hello")
file.write("World")
```
上述代码会将"HelloWorld"连续写入文件,而不会自动换行。如果你想要在每次写入后自动换行,你需要在每次调用write方法后添加换行符"\n"。例如:
```python
with open("file.txt", "w") as file:
file.write("Hello\n")
file.write("World\n")
```
这样就会在文件中显示为:
```
Hello
World
```
