Python vs. Java - Comments | COMP70050: Introduction to Machine Learning | Department of Computing | Imperial College London home article Introduction to Machine Learning COMP70050 Autumn Term 2021/2022 Introduction to Python for Java programmers The Zen of Python Example Python program Python vs. Java - Main method Python vs. Java - Variable declaration Python vs. Java - Semicolons Python vs. Java - Braces Python vs. Java - Comments Running Python Running Python as a script Running Python interactively Basic built-in data types Everything is an object Reserved words Variables - Java vs. Python Python Variables Objects in Python Operators Assignment operator Lists Accessing Lists Modifying Lists Tuples Strings are sequences Formatting strings Sets Dictionaries Grouping data with dict and tuple Control flow Loops Useful objects for loops List comprehensions Functions Function arguments Built-in functions Object-Oriented Programming in Python Constructor Attributes Methods Magic/Dunder methods Inheritance Encapsulation Encapsulation the Pythonic way What about protected? Python modules Custom modules What's in a __name__? Handling text files Reading CSV files Writing to CSV files Handling JSON files Pickle That's a wrap! Python vs. Java - Comments In Python, single-line comments are marked with a #. If you need multiline comments, you can use triple quotes """ or ''' to mark the start and the end of comments. """ This is a program that prints 0, 1, and 2 """
# Single line comment i = 0 # Just like in Java while i < 3:
''' Three single quotes also works '''
print(i)
i += 1
