如何在python 2的同一行上获取不同数据类型的多个输入？ 不能使用 map() 函数，因为输入有混合数据

Question

For ex: i want to take input as A 50 60 70. A is student name and next three numbers are marks of A in 3 subjects. Help me in storing data as above. I have to collect that data for n students.

n=input()
for i in range(0,n):
    St=raw_input(), Eng,Mat,Sci=map(int,raw_input().split())
    print st
    print Eng,Mat,Sci

Error:

    St=raw_input(), Eng,Mat,Sci=map(int,raw_input().split())

Answer 1

You can keep multiple lines of code in one line by separating them with a ; , as long as they're in the same indent level. And since it's python 2, shouldn't n=int(raw_input()) ?

n=int(raw_input())
for i in range(0,n):
    St=raw_input(); Eng,Mat,Sci=map(int,raw_input().split())
    print st
    print Eng,Mat,Sci

But...this isn't a good practice, as it makes your code harder to read. You should separate them on different lines.

n=int(raw_input())
for i in range(0,n):
    St=raw_input()
    Eng,Mat,Sci=map(int,raw_input().split())
    print st
    print Eng,Mat,Sci

Answer 2

In Python, split() function works for taking multiple inputs as a list data type. If you need int,char or string type data then you need to apply typecasting of Python.In the solution,I am using the same approach.

n=int(raw_input())
for i in range(0,n):
     s=str(raw_input())
     St,Eng,Mat,Sci=raw_input().split()
     Eng=int(Eng)
     Mat=int(Mat)
     Sci=int(Sci)
     print St,s
     print Eng,Mat,Sci

Answer 3

I think this would do the job in python 3.

n = int(input())
marks = {}
for i in range(n):
    name, *line = input().split()
    scores = list(map(float, line))
    marks[name] = scores
