What is the Lambda Function

The Lambda function is an expression that can be customized to take the keyword “lambda”, variables and a statement to use those variables to perform a calculation. Other variables can also be assigned to use a lambda function.

Syntax of a Lambda Function

Below shows the syntax of a lambda function and examples how to use it:

lambda name_of_variable1, name_of_variable2...... : mathematical statement

The keyword “lambda” is needed, then all the names of the variables after. Then the colin or “:“ is needed and then a statement to perform an operation with those variables.

Lambda Example

add_two_variables = lambda var1, var2: var1 + var2

print(add_two_variables(3, 5))
# Final Result: 8
