Practical examples

Example 1

In this example, we add 3 to the specified argument x and reteurn the result.

result = lambda x: x + 3

print(result(2))  # 5

Output:

5

Example 2

In this example, we add arguments x and y together.

result = lambda x, y: x + y

print(result(1, 2))  # 3

Output:

3

Example 3

In this example, we multiply the given argument x by 2.

result = lambda x: x * 2

print(result(3))  # 6
