It is possible to include anifstatement inside anotherifstatement. For example, number =5# outer if statementifnumber >=0:# inner if statementifnumber ==0:print('Number is 0')# inner else statementelse:print('Number is positive')# outer else statementelse:print('Number is negative') Run...
These conditions can be used in several ways, most commonly in "if statements" and loops. An "if statement" is written by using theifkeyword. ExampleGet your own Python Server If statement: a =33 b =200 ifb > a: print("b is greater than a") ...
When there is more than just two if conditions in if elif else statements, then it is referred to as if elif else ladder, as it resembles the structure of a ladder in terms of if statements. If one of the if conditions turn out to be true, then the rest of the ladder is just byp...
if (x==4) { printf("x is equal to four\n"); printf("Nothing more to do here.\n"); } printf("The if statement is now over.\n"); Python 中的相同代码如下所示:if x == 4: print "x is equal to four" print "Nothing more to do here." print "The if statement is now over...
Python If Else Statement - Learn how to use if and else statements in Python with practical examples. Master conditional logic in your Python programming.
We now know how to execute some code based on certain conditions. In other words, if the condition is true (execute if block) otherwise execute else block if the condition is false. But there is one more use case in the conditional statements. What if we want to put up one more check...
If you don’t provide an explicit return statement when defining a function, then Python will automatically make the function return None.Even though all expressions are statements, not all statements are expressions. For example, pure assignment statements don’t return any value, as you’ll ...
Introduction to the if Statement We’ll start by looking at the most basic type of if statement. In its simplest form, it looks like this: Python if <expr>: <statement> In the form shown above: <expr> is an expression evaluated in a Boolean context, as discussed in the section on...
As you can see in the above program, all we did was, we started by adding a condition to theifblock, and then used anotherif-elseblock in itselseblock. And we kept on doing the nesting until all the conditions were taken care of. This, however, is a little tedious than usingelif....
