Lambda Functions in Python

What is a lambda function in Python?

• A lambda function in Python is a small anonymous function that can take any number of arguments but can only have one expression.

• A lambda function in Python is a function that can only take one argument and can have multiple expressions.

• A lambda function in Python is a built-in function that can only take one argument.

• A lambda function in Python is a function that can take any number of arguments and can have multiple expressions.

What is the syntax of a lambda function in Python?

• expression : lambda arguments

• lambda arguments : expression

• expression : arguments lambda

• arguments : lambda expression

How do you define a lambda function in Python?

• A lambda function in Python is defined using the lambda keyword followed by the arguments and a colon, then the return statement.

• A lambda function in Python is defined using the lambda keyword followed by the arguments and a colon, then the expression.

• A lambda function in Python is defined using the lambda keyword followed by the arguments and a colon, then the statements.

• A lambda function in Python is defined using the def keyword followed by the function name, arguments, and a colon, then the expression.

What is the purpose of using lambda functions in Python?

• The purpose of using lambda functions in Python is to reduce code complexity.

• The purpose of using lambda functions in Python is to improve code readability.

• The purpose of using lambda functions in Python is to create anonymous functions.

• The purpose of using lambda functions in Python is to increase code performance.

Can a lambda function have multiple arguments in Python?

• Yes

• Only if it is defined as a named function

• Sometimes

• No

What is the difference between a lambda function and a regular function in Python?

• A lambda function is a function that requires a return statement.

• A regular function is an anonymous function that can be defined in a single line and does not require a return statement.

• A lambda function is a named function that can have multiple lines of code and can be reused multiple times.

• A lambda function is an anonymous function that can be defined in a single line and does not require a return statement. A regular function is a named function that can have multiple lines of code and can be reused multiple times.

How do you call a lambda function in Python?

• By using the name of the lambda function followed by parentheses.

• By using the 'execute' function on the lambda function.

• By using the 'call' method on the lambda function.

• By using the 'lambda' keyword followed by parentheses.

What are the advantages of using lambda functions in Python?

• Lambda functions in Python have several advantages, including being concise, anonymous, and useful for one-time functions and as arguments in higher-order functions.

• Lambda functions in Python are slower than regular functions.

• Lambda functions in Python can only be used for simple tasks.

• Lambda functions in Python are difficult to debug.

What are the limitations of lambda functions in Python?

• Lambda functions in Python have the same functionality as regular functions.

• Lambda functions in Python have no limitations.

• Lambda functions in Python have limitations such as only being able to contain a single expression, not being able to contain statements or multiple lines of code, and having limited functionality compared to regular functions.

• Lambda functions in Python can contain multiple expressions.

How do you use a lambda function with the map() function in Python?

• Define the lambda function inline and pass it as the first argument to the map() function.

• Define the lambda function as a separate function and pass it as the second argument to the map() function.

• Define the lambda function inline and pass it as the second argument to the map() function.

• Define the lambda function as a separate function and pass it as the first argument to the map() function.
