How Do I Handle Multiline Input in Python 3?

Handling Multiline Input in Python

While working with input in Python, you may encounter the need to handle multiple lines of input. A common question arises in this context: why doesn't Python 3 include a function like raw_input for multiline input handling?

Understanding the 'Input' Function

In Python 3, the input() function reads a single line of input from the user. It does not allow line breaks within the input.

Solution for Multiline Input Handling

To handle multiline input in Python, you can implement a loop that continues reading until the user enters an "End of File" (EOF) signal (Ctrl-D on Unix-like systems or Ctrl-Z on Windows).

Code Snippet

Here's a code snippet that demonstrates how to read and store multiline input in a list:

print("Enter/Paste your content. Ctrl-D or Ctrl-Z (Windows) to save it.")
contents = []
while True:
    try:
        line = input()
    except EOFError:
        break
    contents.append(line)

This code snippet will continue prompting the user for input until they enter an EOF signal, effectively capturing all lines of input into the contents list.

Storing the Input

The input lines are stored line by line in the contents list. You can then work with the input line by line, perform any necessary processing, or store it in a file as required.
