This cheat sheet includes the materials I’ve covered in my Python tutorial for Beginners on YouTube. Both the YouTube tutorial and this cheat cover the core
Python has integers and floats. Integers are simply whole numbers, like 314, 500, and 716. Floats, meanwhile, are fractional numbers like 3.14, 2.867, 76.88887. You can use the type method to check the value of an object. In the last example, pi is the variable name, while 3.14 is the value.
If you have a basic understanding of Python and want an easy reference while developing Python applications, this Python 3 cheat sheet is for you. Read on as we walk you through various Python commands or functions, operators, data types, data structures, and much more.
Note: Python has four numeric types (integer, float, long and complex) and several sequence types including strings, lists, tuples, bytearrays, buffers, and xrange objects. # for example: if x < 5: Most Python objects have methods and attributes.
