map(lambda a,b,c: (a,b,c), name, age, nation)

name=['a','b','c']
age=[10,11,12]
nation=['中国','にほん','Deutsch']
U1=list(zip(name,age,nation))
print(U1)
U2 = map(lambda a,b,c: (a,b,c), name, age, nation)
print(list(U2))

The first errorNoneType is for None object, so it is normal that it cannot be output.
NoneType is the type for the None object, which is an object that indicates no value. You cannot add it to strings or other objects.

The Python map() method doesn’t seem to be how you use it. As far as I know, it should be like this.
Description
is very simple. The first parameter receives a function name, and the second parameter receives an iterable object.
Syntax
map(f, iterable)
Basically equals:
[f(x) for x in iterable]
Example

>>> def add100(x):
...     return x+100
... 
>>> hh = [11,22,33]
>>> map(add100,hh)
[111, 122, 133]
