If the length of list is zero, the function immediately terminates. Otherwise, it continues until the end. If the condition in the assert statement is false, an AssertionError will be raised: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 a = [] print(avg_value(a)) AssertionError: No...
we have a technique calledMnemonic(记忆的).The idea is when you choose a variable name,you should choose a variable name to be sensible and Python doesnt care whether you choose mnemonic variable names or not. Assignment Statements: An assignment statement consists of an expression on the right...
if-else Syntax in C: The basic syntax of the “if-else” statement is as follows: if (condition) { // Code block executed if the condition is true } else { // Code block executed if the condition is false } Mechanism of if-else statement in C Initiated by the “if” keyword, th...
So, operators must be part of expressions, which you can build using Python objects as operands.So, what is an expression anyway? Python has simple and compound statements. A simple statement is a construct that occupies a single logical line, like an assignment statement. A compound statement...
