Python If .. Else
Python Tutorial » Python If .. Else
Python supports logical conditions from mathematics as:
1. Equals: a == b
2. Not Equals: a != b
3. Greater than: a > b
4. Less than: a < b
5. Greater than or equal to: a >= b
6. Less than or equal to: a <= b
These conditions can be used in several ways, most commonly in "if statements" and loops.
Example: of "if" statement
Output:
y is greater than x
x = 320
y = 42
if x > y:
print("x greather than y")
y = 42
if x > y:
print("x greather than y")
Output:
y is greater than x
Else statemnt - example
Example: Dictionaries cannot have two items with the same key
x is greater than y
x = 320
y = 42
if x > y:
print("y is greather than x")
else:
print("x is greater than y")
Output: y = 42
if x > y:
print("y is greather than x")
else:
print("x is greater than y")
x is greater than y
Elif statement - example
Example: elif is short for else if statement. It allows us to check for multiple expressions.
q and w are equal
q = 2433
w = 2433
if w > q:
print("w is greather than q")
elif q == w:
print("q and w are equal")
Output:w = 2433
if w > q:
print("w is greather than q")
elif q == w:
print("q and w are equal")
q and w are equal
if .. elif .. slse statements
Example: if .. elif .. slse
x is greater than y
x = 457
y = 28
if y > x:
print("y is greater than x")
elif x == y:
print("x and y are equal")
else:
print("x is greater than y")
Output:y = 28
if y > x:
print("y is greater than x")
elif x == y:
print("x and y are equal")
else:
print("x is greater than y")
x is greater than y
