This is trueFor example, check the following example-
x = 80
if x >= 40:
print("Success")
Output:
Successif…else
x = 80
if x >= 40:
print("Success")
else:
print("Failure")Output:

x = 80
if x > 100:
print("Wrong value")
elif x > 80:
print("Excellent score")
elif x >= 40:
print("Good score")
else:
print("Fail")Output:
Good scoreNested if…else
x = 80
if x > 40:
print("X is greater than 40")
if x >= 80:
if x == 100:
print("Perfect Score")
elif x >= 90:
print('Excellent score')
