In Python, you can add comments to your code using the hash symbol (#). Anything that comes after the hash symbol in a line of code will be considered a comment and will be ignored by the interpreter. Here's an example:
# This is a comment in Python
print("Hello, world!") # This is also a comment
In the above code, the first line is a comment that doesn't affect the program in any way. The second line prints the string "Hello, world!", and the third line is another comment.
You can also add comments that span multiple lines by using triple quotes ("""). Here's an example:
"""
This is a multi-line comment in Python.
You can add as many lines as you want here.
"""
print("Hello, world!") # This is not part of the comment
In the above code, the first three lines are a multi-line comment that doesn't affect the program. The fourth line prints the string "Hello, world!", and the fifth line is a regular comment.
