Theandkeyword is a logical operator, and is used to combine conditional statements: Example Test ifais greater thanb, AND ifcis greater thana: a =200 b =33 c =500 ifa > b and c > a: print("Both conditions are True") Try it Yourself » ...
Logical Operators to Add Multiple Conditions If needed, we can use logical operators such asandandorto create complex conditions to work with anifstatement. age =35salary =6000 # add two conditions using and operatorifage >=30andsalary >=5000: print('Eligible for the premium membership.')els...
Note: In the Python documentation, a group of statements defined by indentation is often referred to as a suite. This tutorial series uses the terms block and suite interchangeably.Consider this script file foo.py:Python 1if 'foo' in ['bar', 'baz', 'qux']: 2 print('Expression was ...
IF-ELSE --> CONDITION2: condition1 is false and condition2 is true IF-ELSE --> ELSE: all conditions are false 上面的关系图展示了多个if else语句的逻辑关系,当条件1为真时执行第一个代码块,当条件1为假且条件2为真时执行第二个代码块,当所有条件都为假时执行最后一个代码块。 多个if else语句的...
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语句首先评估条件的结果值，如果结果为 True, 则执行语句块中的语句序列，然后控制转向程序的下一条语句。如果结果为 False, 语句块中的语句会被跳过。A statement block is a sequence of one or more statements executed after the conditions are met, and the statements in the statement block express the...

With these operators, you can create compound conditions.In the following sections, you’ll learn how the Python Boolean operators work. Especially, you’ll learn that some of them behave differently when you use them with Boolean values or with regular objects as operands....
1"""2This function should check the value of the num variable and3return the string representation of the interval it is in Use if, elif,4and else statements to check if num falls in the range 1-5, 6-10,511-15, or 16-20. Then return the correct interval as a string, like6"1-...
12. What are Python’s conditional statements? Answer: Python uses if, elif, and else to execute code based on conditions. Example: age = 18 if age < 18: print("Minor") elif age == 18: print("Just turned adult") else: print("Adult") ...
