Conditional statements (if, elif, else)?
if…elif…else are conditional statements that provide you with the choice making that is required while you want to execute code based totally on a particular circumstance.
The if…elif…else statement utilized in Python facilitates automate that choice making method.
If Statements
The if statements is taken into consideration the most effective of the 3 and makes a choice based totally on whether the condition is true or no longer. If the condition is genuine, it prints out the indented expression. If the condition is false, it skips printing the indented expression.
Example
if 10 > 5:
print("10 greater than 5")
print("Program ended")
Output
10 greater than 5Program ended
If..else Statements
The if-else circumstance provides an extra step inside the choice-making manner in comparison to the simple if assertion. the start of an if-else statement operates much like a easy if assertion; but, if the situation is fake, in preference to printing not anything, the indented expression below else might be printed.
Example
# if..else statement
x = 3
if x == 4:
print("Yes")
else:
print("No")
Output
No
if-elif statements
The if-elif statement is shortcut of if..else chain. While using if-elif statement at the end else block is added which is performed if none of the above if-elif statement is true.
Example
grade = 75
if grade >= 90:
print("Grade: A")
elif grade >= 80:
print("Grade: B")
elif grade >= 70:
print("Grade: C")
else:
print("Grade: D")
Output:
Grade: C
Nested if
if assertion can also be checked internal different if announcement. This conditional statement is known as a nested if assertion. because of this internal if condition may be checked simplest if outer if situation is actual and through this, we will see a couple of conditions to be happy.
Example
Nested if statement example
num = 10
if num > 5:
print("Bigger than 5")
if num <= 15:
print("Between 5 and 15")
Output
Bigger than 5 Between 5 and 15
