reading multiple lines of different data types using python

Question

I have an input where the first line is a string and the next line contains three integers:

1 2 3

I have to store the string from the first line to a separate variable and the 3 integers in separate variables. The input is comming fromstdin.

I tried to use sys.stdin.read() but it reads the entire input as one entity. How to split it to separate variables?

Are you familiar with the built-in [`input()`](https://docs.python.org/3/library/functions.html#input) function? — Tomerikoo, Sep 17 '20 at 13:04
Please update the question to show the code you’ve written so far to solve the issue. — S3DEV, Sep 17 '20 at 13:05

use readline() it helps in reading input per line.

import sys
string_inp=sys.stdin.readline()
a,b,c=map(int,sys.stdin.readline().split())
print(string_inp)
print(a,b,c)

This way, you'll get integers in 3 different variables and string in another.

use input as:

why not use `input()`? – Tomerikoo Sep 17 '20 at 13:19
@Tomerikoo you can definately use ```input()``` but since OP tried using ```sys.stdin.read()```, I am only trying to point out how a small change could have fixed his problem. – Yash Sep 17 '20 at 13:21
Oh true, I didn't notice OP said he is using that. In that case that's a good correction but I would still mention about using `input()` as this is the idiomatic way of getting user input... – Tomerikoo Sep 17 '20 at 13:56

Try this:

ip = input().split()

text = ip[0]
num1, num2, num3 = (int(x) for x in ip[1:])

print(text, num1, num2, num3)
