How to Prevent Newline Insertion in Python's `raw_input()` and `input()` Functions?

Preventing Newline Insertion in Input Functions

This issue arises when using the raw_input() or input() functions (for Python 2.x and 3.x, respectively) because they automatically add a newline after user input. This behavior is problematic when attempting to remove the newline and place user input directly after a printed string.

Despite common belief, it is impossible to prevent raw_input() from inserting a newline. However, a workaround exists to reposition the cursor to the previous line after input has been received.

Repositioning the Cursor

A clever solution involves navigating the cursor to highlight the previous line using ANSI escape sequences. By specifying the length of the user input (x) and the length of the raw_input() prompt (y), the cursor can be repositioned accordingly:

print '3[{}C3[1A'.format(len(x) + y),

In this code:
