For instance, in C we can do something like this:
C
// Reads two values in one linescanf("%d %d", &x, &y) |
One solution is to use raw_input() two times.
Python3
x, y = input(), input() |
Another solution is to use split()
Python3
x, y = input().split() |
Note that we don’t have to explicitly specify split(‘ ‘) because split() uses any whitespace characters as a delimiter as default. One thing to note in the above Python code is, both x and y would be of string. We can convert them to int using another line
x, y = [int(x), int(y)] # We can also use list comprehension x, y = [int(x) for x in [x, y]]
Below is complete one line code to read two integer variables from standard input using split and list comprehension
Python3
# Reads two numbers from input and typecasts them to int using# list comprehensionx, y = [int(x) for x in input().split()] |
Python3
# Reads two numbers from input and typecasts them to int using# map functionx, y = map(int, input().split()) |
Instead of using the input function to read a line of input from the user and then processing the line to extract the values, you can use the sys.stdin.readline function to read a line of input and then use the split method and a list comprehension to extract and convert the values to the desired type.
Python3
import sys# Read a line of input# Split the line into a list of values# Extract and convert the values to integers using a list comprehensionline = [int(x) for x in sys.stdin.readline().split() ] |
