You can use a lambda function with the map() function in Python to apply a function to each element of a sequence and return a new sequence containing the results. The map() function takes two arguments: a function to apply to each element of the sequence, and the sequence to map. It returns a new sequence containing the results of applying the function to each element of the original sequence. 

Here is an example:

numbers = [1, 2, 3, 4, 5]
squares = list(map(lambda x: x**2, numbers))
print(squares)
 

In this example, we have a list of numbers from 1 to 5. We want to create a new list containing the square of each number in the original list. We use the map() function along with a lambda function to accomplish this.

The lambda function takes one argument x, which represents an element from the numbers list. The lambda function returns x**2, which is the square of x. The map() function applies this lambda function to each element of the numbers list, and returns a new list containing the results of applying the lambda function to each element.

We assign this new list to the variable squares, and then print it to the console using the print() function. The output of this code will be [1, 4, 9, 16, 25], which is the list of squares of each number from the original list.
