KeyError: 'a' while while writing a program in python

Question

   a=input('enter the name\n')
   b=input('enter the age\n')

   print('your name is {a} and your age is {b}'.format(a,b))

我在上面運行一段代碼，但在 python 中出現以下錯誤：

Traceback (most recent call last):
  File "main.py", line 4, in <module>
    print('your name is {a} and your age is {b}'.format(a,b))
KeyError: 'a'

Answer 1

您正在組合兩種不同的語法。 嘗試以下操作之一：

print('your name is {} and your age is {}'.format(a,b))

或者

print(f'your name is {a} and your age is {b}')  # notice the f in the begining
