Traceback (most recent call last): This is a running error .
Wrong background ： Error in function call for multivalued parameter .
When I was practicing this problem , Use tuples as multivalued arguments to functions . When making function calls , There is a misuse of dictionary rules .
1. Dictionary key, You can't use "" contain .
2. Key value pairs are used in the middle = Not the comparison operator ==
It directly leads to the appearance of the top Traceback The reason for the mistake is , Undefined variable name used .
summary ：debug Your ability needs to be proficient .
Attach error code ：
def demo(num, *args, **kwargs):
print(num)
print(args)
print(kwargs)
print("")
print(" The correct sample ")
demo(1)
demo(1, 2, 3,)
demo(5, 6, 7, name=" Xiao Ming ", age=18)
# Error model
print(" demonstration 1, There is no definition in the code name This variable name , No... Was found during the comparison operation , Therefore, the program reports an error ")
demo(5, 6, 7, name == " Xiao Ming ")
print(" demonstration 2, The result of the comparison operation is a Boolean value ")
demo(5, 6, 7, "name" == " Xiao Ming ")
