如何在python中拆分长f字符串？

Question

我收到line too long pep8 E501问题。

f'Leave Request created successfully. Approvers sent the request for approval: {leave_approver_list}'

我尝试使用多行字符串，但这会带来\n，这会破坏我的测试：

f'''Leave Request created successfully.
Approvers sent the request for approval: {leave_approver_list}'''

如何保持单行并通过pep8 linting

Answer 1

使用括号和string literal concatenation：

msg = (
         f'Leave Request created successfully. '
         f'Approvers sent the request for approval: {leave_approver_list}'
)

请注意，第一个文字不需要f，但我将其包含在内以保持一致性/可读性。

Answer 2

只需添加反斜杠\字符：

f'''Leave Request created successfully.\
Approvers sent the request for approval: {leave_approver_list}'''

Answer 3

你确实需要一个换行符。但f需要预先设置在第二行：

'Leave Request created successfully.'\ 
f'Approvers sent the request for approval: {leave_approver_list}'

这是一个小小的演示：

In [97]: a = 123

In [98]: 'foo_'\
    ...: f'bar_{a}'
Out[98]: 'foo_bar_123'
