Common Operations

There are some functions which can be applied on all collections. Here we will see details related to list and set.

  • in - check if element exists

  • len - to get the number of elements.

  • sorted - to sort the data (original collection will be untouched). Typically, we assign the result of sorting to a new collection.

  • sum, min, max, etc - arithmetic operations.

  • There can be more such functions.

l = [1, 2, 3, 4] # list

1 in l

True

5 in l

False

len(l)

sorted(l)

[1, 2, 3, 4]

sum(l)

s = {1, 2, 3, 4} # set

1 in s

True

5 in s

False

len(s)
