Python转义“{}”符号

Question

我有一个字符串，我在其中使用字符串格式：

'SELECT {} FROM {} WHERE country={} AND \{\}'.format("apples", "tables","home")

目前这不起作用;如何转义{和}以便打印字符串：

SELECT apples FROM tables WHERE country=home AND {}

Answer 1

您可以使用{}

来转义{{}}序列

>>> 'SELECT {} FROM {} WHERE country={} AND {{}}'.format("apples", "tables","home")
'SELECT apples FROM tables WHERE country=home AND {}'
