As the code grows longer and becomes more complicated, comments prove to be a good way of explaining the code. In Python, we use the#character to initiate a comment. We use this for declaring single-line comments. Most programming languages support multi-line comments also. However, in Pytho...
When we need to comment on multiple lines/statements, there are two ways to do this, either comment each line or create multiline comments (or block comment).In C / C++, we use /*...*/ for the multiline comment, but in Python programming language, we have two ways to comment a ...
In Python, you can comment out a block of code by using the "#" symbol at the beginning of each line. For example: # This is a comment # print("This line of code will not be executed") print("This is the main code and will be executed") Try it Yourself » Copy Watch a...
