Conditional statements in python performs actions (or) computations that depends on a certain condition(true(or) false).
Python supports different types of control statements. So, let us discuss one by one in detailed.
Python If is a statement (or) a group of statements executes when a particular condition satisfies.
If (condition = true)
Print (“condition satisfies(true)”)
Would you like to know how people use python for Data Science
In the above statement, there is no logic to execute if the IF condition fails. So this python if –else statement satisfies the condition.
As said above IF block executes if the condition satisfies. Otherwise Else block executes.
if(Condition =true) Statement 1 Else Statement 2
Ex : i=1
If (i==1) Print(Since i=1 true condition executes) Else Print(Since I not equal to 1 false condition executes)
There are some situations, where an operation needs to satisfy several conditions. Then we use Nested if condition. This is also called the Multiple If statements.
If(condition = true) Statement 1 If(condition=true) Statement 2 elif(condition =true) statement 3 else statement 4 Ex: I=10 If(i<100) Print(’10 is less than 100’) If(i==20) Print(’10 equals to 20’) Elif Print(‘we cannot equate 10 with 20’) Else Print(‘There is no true condition in the statements. So else block is executed’).
Since these concepts were common in many programming languages like C, JAVA .So I advice you to practice more code on this loop. Feel free to clarify the doubts at Software training institutes
As like above, we cannot expect only one / two conditions. In some, there may be a 100 (or) even maybe a 1000 conditions. Moreover, there is only a need for one block of statements to execute if the condition satisfies. So in those cases, we uses break statement.
If (condition 1 ) Statement 1 Break If(condition 1) Statement 2 Break Else Statement 3
I = 20 If ( 1==10) Print(‘I not equal to 20’) Break If(i==20) Print(‘Condition satisfies’) Break Else Print(‘No condition satisfies’)
This is somewhat similar to the Break statement. Hence the condition satisfies it skip the current statement and forces to process the next iteration.
Since these were common in every programming languages like C, JAVA, So, I would like to leave the code for you as an exercise. And if you were struck up anywhere python online training will guide you
