The things i learned form todays python course:
- Lambda function:
It is one most important important function used in python programming.
on going depth i found that it is anonymous function used in code .It is mainly used in on line function for example :
numbers = [1, 2, 3, 4, 5]
squared = list(map(lambda x: x ** 2, numbers))
print(squared) # Output: [1, 4, 9, 16, 25]
In above example list is given and in that list using lambda function we found the square of the whole list i.e in sqaured variable.
The basic idea used in above example or anyother example or program is used like :
lambda(parameter:expression)
or lambda(argumensts:expression)
- Map:
It helps to iterate every single value present in the list.
taking an example:
numbers = [1, 2, 3, 4, 5]
squared = list(map(lambda x: x ** 2, numbers))
print(squared) # Output: [1, 4, 9, 16, 25]
In above example map is used for sqauring every single of the value in the list .
Also some basic stuffs like how swap values in the list ,more about IDctionary and all .
This much only for today.
