Step by Step solution about How to resolve the algorithm Terminal control/Inverse video step by step in the Python programming language

This Python program demonstrates how to print text in reversed video mode on a terminal using escape sequences. Here's a breakdown of the code:

1. #!/usr/bin/env python : This line is known as a "shebang" line and specifies that the script should be executed using the Python interpreter. It's commonly used in Unix-like systems, but has no effect in Windows.

2. print "\033[7mReversed\033[m Normal" : This line is the main part of the program and does the following:

• "\033[7m" : This is an escape sequence that instructs the terminal to enter "reverse video" mode, where the background and foreground colors are swapped.

• "Reversed" : This is the text that will be printed in reversed video mode.

• "\033[m" : This escape sequence resets the terminal to its normal mode, exiting reversed video mode.

• "Normal" : This is the text that will be printed after the terminal returns to its normal mode.

When you run this script on a terminal that supports escape sequences, it will print "Reversed" in reversed video mode, followed by "Normal" in normal mode.

#!/usr/bin/env python

print "\033[7mReversed\033[m Normal"
