While Statement 2.1 featuresThe essence of the while loop is to allow the computer to repeat the same thing (that is, the while loop is a conditional loop, which includes: 1. Condition count cycle, 2 conditional infinite loop)This condition means: conditional expressionThe same thing means: The block of code that the while loop body containsRepeat things such as: from 1 to 10000, ask for all the odd numbers within 1-10000, the service waits for a connec

statement block is a set of statements that are executed one or more times when the condition is true. In Python, a colon (:) is used to identify the beginning of a statement block, and each statement in the block is indented. When you fall back to the same indentation as a block that has already been closed, it means that the current block is over.Four. Conditional and conditional statements4.1 That's what Boolean variables are for.The following val

statementThe for and while loops in Python have an optional else branch (such as an optional else branch in the IF statement) that executes after the loop iteration is completed normally. means that the normal loop exits, the Else branch is executed, that is, there is no break statement in the loop body, no return statement, or no exception appears.· An example of a normal exit loop: for I in range (5):Pr
