![]() ![]() The elif keyword prompts your program to try another condition if the previous one is not true. If the condition is false, the “else” block code is executed. If the condition is true, the “if” block code is executed. The if-else statement is used to execute both the true and false parts of a given condition. The “and” operator’s Truth Table: Expression The “or not” operator’s Truth Table: Expression The “or” operator’s Truth Table: Expression There are three Boolean operators in Python - and, or, and not. Use the “is” or “is not” operators, or use implicit boolean evaluation. If you want to evaluate a boolean operation in Python, never use = or != operators. Flow Control Comparison OperatorsĬomparison operators are used to compare two values and evaluate True or False depending on the values you give them. The above function will print 4 as a result. If in case you don’t use the return statement, None is returned by default. Greet_user(“John”, “Smith”) Keyword Argument Example:Ĭalculate_total(order=30, shipping=8, tax=0.1)įunctions can return values. There are two types of values - positional arguments (their position matters) and keyword arguments (their position doesn’t matter). Parameters are the placeholders for data to pass through functions. It is also easier to find bugs in a small chunk rather than going through the entire program. These chunks are easier to read and maintain. Functionsįunctions in Python are used to break up the code into small chunks. In the above example, price is an integer (a whole number with no decimal points), rating is a floating-point number (a number with a decimal point), course_name is a string (a sequence of characters), and published is a boolean.īoolean values in Python can be True or False. Variables are used to temporarily store data in the computer’s memory. Other common data types in Python are lists, dictionaries, and tuples. This means that if you have already defined one, you cannot change it later on. Also, remember that strings are immutable in Python. Integer (int)Īn integer is used to represent an object such as “number 5”.Įxample: -2, -1, 0, 1, 2, 3 Floating-Point Number (float)įloat is used to represent floating-point numbers.Įxample: -1.25, -1.0, – 0.5, 0.0, 0.5, 1.0, 1.25 StringĪ string is used to modify a sequence of characters. The three most used data types in Python are integers, floating-point numbers, and string. In Python, every value is referred to as an object and every object has a specific data type. Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off Sets each bit to 1 if only one of two bits is 1 Sets each bit to 1 if one of two bits is 1 Returns True if both variables are not the same objectīitwise operators are used to compare binary numbers. Returns True if both variables are the same object Identity operators are used to compare the objects to see if they are actually the same object with the same memory location. ![]()
