Built in functions in Python.

Built in functions:

sum()

sum () function is used to add the all elements of list.

marks=[70,60,55,80,75] temp=sum(marks) print(temp) avg=float(temp/len(marks)) print(avg)

output:

340 68.0

len()

l1=[10,20,30,40,50] print(len(l1))

output:

5

output:

50

min()

l1=[10,20,30,40,50] print(min(l1))

output:

10

shuffle()

This method is used to shuffle the value present in the list. To used the memthod shuffle, we have to import module.

import random l1=[10,20,30,40,50] random.shuffle(l1) print(l1)

output:

[50, 10, 30, 40, 20]

join()
