How Does the sys.stdin.readline() Method Work in Python?

Question

Khushi Singh · Answer

The sys.stdin.readline method in 
Python allows users to read input from standard input (stdin) through faster data acquisition in competitive programming situations, along with large data applications.
Explanation:
Sys module contains this method therefore, you must first import the sys module to use it.The readline function of the sys.stdin module permits users to input multiple lines of keyboard interaction including a termination character 
 to indicate the end of input.The method returns a string value that contains the trailing newline except when reading the last character of the input.The strip or rstrip methods help eliminate newline characters from strings.
The method outperforms input() in terms of speed when clearing several or extensive input entries.
Code Example
import sys
print("Enter your name:")
name = sys.stdin.readline().strip()  # removes the newline character
print(f"Hello, {name}!")
Output
Enter your name:
Alice
Hello, Alice!
When to Use:
Reading input in competitive programming.
and The function enables the handling of batch input, which includes file reading or data streams.
and Situations where performance is critical.
and The sys.stdin.readline() method stands as a prime input solution because it offers rapid processing of extensive or numerous inputs within the
Python environment.
