python f-string 字典使用问题

Question

f-string 格式化字符串中，使用字典出现问题.错误如下，使用双引号后错误消失,不知道如何解决单引号的问题

>>>a={'name':'wang','ange':12}
>>>print(f'name is {a['name']}')
  File "<input>", line 1
    print(f'name is {a['name']}')
                        ^
SyntaxError: f-string: unmatched '['
>>>print(f"name is {a['name']}")
name is wang
>>>print(f'name is {a[\'name\']}')
  File "<input>", line 1
    print(f'name is {a[\'name\']}')
                                  ^
SyntaxError: f-string expression part cannot include a backslash
>>>

如果在f-string整字串用单引号的话，在{}中就要用双引号。

print(f'name is {a["name"]}')
