How do I read from stdin in Python?
In Python, you can read from standard input (stdin) using the input() function. This function blocks execution and waits for the user to enter some text, which is then returned as a string. For example:
input_string = input()
print(input_string)
Alternatively, you can use the sys.stdin object, which is a file-like object that can be read from using the standard file I/O methods, such as read(), readline(), and readlines().
For example:
import sys
input_string = sys.stdin.read()
print(input_string)
You can also use the fileinput library for reading input from stdin, it has several useful features like reading line by line, looping over multiple files, and providing a convenient way to access command line arguments.
import fileinput
for line in fileinput.input():
print(line)
