Python For Loops. A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like the for keyword in other programming languages, and works more like an iterator method as found in …

The while Loop. With the while loop we can execute a set of statements as long as a condition is true.

You can loop through a dictionary by using a for loop. When looping through a dictionary, the return value are the keys of the dictionary, but there are methods to return the values as well. Example

When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop: Syntax for ( statement 1 ; statement 2 ; statement 3 ) { // code block to be executed }

When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop: Syntax for ( statement 1 ; statement 2 ; statement 3 ) { // code block to be executed }

When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop: Syntax for ( expression 1 ; expression 2 ; expression 3 ) {

Expression 1 sets a variable before the loop starts (let i = 0). Expression 2 defines the condition for the loop to run (i must be less than 5). Expression 3 increases a value (i++) each time the code block in the loop has been executed.

Python Conditions and If statements. Python supports the usual logical conditions from mathematics: Equals: a == b; Not Equals: a != b; Less than: a < b; Less than or equal to: a <= b; Greater than: a > b; Greater than or equal to: a >= b; These conditions can be used in several ways, most commonly in "if statements" and loops.

Python Collections (Arrays) There are four collection data types in the Python programming language: List is a collection which is ordered and changeable. Allows duplicate members. Tuple is a collection which is ordered and unchangeable. Allows duplicate members. Set is a collection which is unordered, unchangeable*, and unindexed. No duplicate ...
