first, we assign value 22 to ravi variable (consider the age of ravi is 22) and check if ravi is not equal to 20. This condition becomes true and the body of the if statement is executed.
The equality operator (==) tests if two variables have an equal value. Given variable x=3 and y=3, we can test for equality using the statement if x == y, which will return true. If we change either x or y, it would return false. It looks like the assignment operator (=) , b...
if age >= 16: print("You can enroll in the Intellipaat course!") Output: Explanation: Here, the program checks if the age is greater than or equal to 16, prints a message if the condition is true, and does not return any output if the condition is False. 2. If…Else Statement in...

The if, if...else statement examples: Here, we will learn about simple if else by using some of the small example codes. By Pankaj Singh Last updated : April 09, 2023 Example 1: Check whether a given number is 10 or nota=int(input("Enter A : ")) if a==10: print("Equal to...
A string is a palindrome if the string read from left to right is equal to the string read from right to left i.e. if the actual string is equal to the reversed string. Problem statementGiven a string, you have to implement a python program to check whether a string is a palindrome ...
IndexError:stringindexoutofrange 可以使用try/except来捕获异常。作为入门示例,下面是简单版的格式: 1 2 3 4 5 6try: statement1 ... statementN except <ERRORTYPE>: ...statementS... 例如,try中是要监视正确执行与否的语句,ERRORTYPE是要监视的错误类型。
l = [1, 2, 'hello', 'world'] # 列表中同时含有int和string类型的元素 l [1, 2, 'hello', 'world'] tup = ('jason', 22) # 元组中同时含有int和string类型的元素 tup ('jason', 22) 其次,我们必须掌握它们的区别。 列表是动态的,长度大小不固定,可以随意地增加、删减或者改变元素(mutable)。
Hence statement inside the if condition is executed. second string is not empty, so it will become True inside if condition. not will convert True to False. Hence statement inside the else block is executed. last string not empty, so it will become True inside if condition. not will ...
Python当中的判断语句非常简单,并且Python不支持switch,所以即使是多个条件,我们也只能罗列if-else。 # Let's just make a variable some_var = 5 # Here is an if statement. Indentation is significant in Python! # Convention is to use four spaces, not tabs. ...
