Lambda functions
Lambda functions
• Similar to user defined functions , but without a name
• Called as Anonymous functions
• Efficient for simple expressions , ie for expressions with single line of
statement.
• Useful when functions are used once.
Define lambda functions
lamdba – keyword for defining anonymous functions
argument(s) – variable to hold the value to be passed into the function, can have
multiple values depending on the need.
Expression – code to be executed in the lambda function.
Anonymous function – does not have a return keyword , as it automatically returns the
result of the expression, once executed.
Donot use lambda functions for complex structures like if else , loops, define user
defined functions for the complex structure.
Functions- example
Lambda function
• Invoke a lambda function immediately
Iterables
• Anything that consists of series of values like, characters, numbers
etc. In python it is String, lists , ranges, tuples, and so on.
• Lambda is used with two other functions
• 1. filter
• 2. map
Filter
• Focus on a specific value in an iterable.
• Ex:
