# Ternary operator in Python: 6 possible methods

There are many ways to make a ternary operator in Python but there exists a one-liner if-else statement that is usually called the ternary or conditional operator in Python. There are more ways that can act as or simulate a ternary operator in Python. Let’s explore most of them today.

## 1. if-else

Syntax:

`<expression 1> if <condition> else <expression 2>`

Explanation:

if the `condition` is true then `expression 1` will be evaluated else `expression 2` will be evaluated.

Example 1:

``print(5 if 7>6 else 4)``

Here, `condition` is 7>6, `expression 1` is 5, and `expression 2` is 4

Output:

`5`

Example 2:

``````# assigning variable according to condition
a = 5 if 7>6 else 4
print(a)``````

Output:

`5`

## 2. Using List

Syntax:

`[expression 1, expression 2][condition]`

if the `condition` is true, `expression 2` will be evaluated else `expression 1` will be evaluated.

Example 1:

``````a = 45>55
b = ['on_false', 'on_true'][a]
print(b)``````

Output:

`on_false`

Example 2:

``````a = 55 > 45
b = ['expression 1', 'expression 2'][a]
print(b)``````

Output:

`expression 2`

## 3. Using Tuple

Syntax:

`(expression 1, expression 2)[condition]`

Explanation:

if the `condition` is true, `expression 2` will be evaluated else `expression 1` will be evaluated.

Example 1:

``````a = True
b = ('expression 1', 'expression 2')[a]
print(b)``````

Output:

`expression 2`

Example 2:

``````a = False
b = ('expression 1', 'expression 2')[a]
print(b)``````

Output:

`expression 1`

## 4. Using dictionary

Syntax:

`{True: 'on_true', False: 'on_false'}[condition]`

Explanation:

if the `condition` is true `True: 'on_true'` will be evaluated else `False: 'on_false'`.

Example 1:

``````a = 45 > 55
b = {True: 'true', False: 'false'}[a]
print(b)``````

Output:

`false`

Example 2:

``````a = 55 > 45
b = {True: 'true', False: 'false'}[a]
print(b)``````

Output:

`true`

## 5. Using tuple and lambda

According to this solution on StackOverflow, there may be some bugs in the 2nd, 3rd, and 4th methods so using the lambda function will be a good option.

Syntax:

`(lambda: 'falseValue', lambda: 'trueValue')[condition]()`

## 6. Logical `and` and `or`

Syntax:

`condition and on_true or on_false`

Example 1:

``````a = True
b = a and 'on_true' or 'on_false'
print(b)``````

Output:

`on_true`

Example 2:

``````a = 45 > 55
b = a and 'true' or 'false'
print(b)``````

Output:

`false`
