Sys.stdin.readline()
Stdin stands for standard input which is a stream from which the program reads its input data. This method is slightly different from the input() method as it also reads the escape character entered by the user. More this method also provides the parameter for the size i.e. how many characters it can read at a time.
Example:
# Python program to demonstrate # sys.stdin.readline() import sys name = sys.stdin.readline() print(name) num = sys.stdin.readline(2) print(num) |
Output:
Difference between Input and sys.stdin.readline() function.
| Input() | sys.stdin.readline() |
|---|---|
| The input takes input from the user but does not read escape character. | The readline() also takes input from the user but also reads the escape character. |
| It has a prompt that represents the default value before the user input. | Readline has a parameter named size, Which is a non-negative number, it actually defines the bytes to be read. |
Difference between input() and sys.stdin.readline()
Python is a widely used general-purpose language that can be used for many purposes. Taking input in any language is as important as breathing for humans. Python provides various methods for taking input. However, we all may get confused about how each method is different from one another. In this article, we will discuss about two such methods i.e input() and sys.stdin.readline().
