Common Operations

There are some functions which can be applied on all collections. Here we will see details related to tuple and dict using Python as programming language.

  • in - check if element exists in the tuple

  • in can also be used on dict. It checks if the key exists in the dict.

  • 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. In case of dict, the operations will be performed on key.

  • There can be more such functions.

t = (1, 2, 3, 4) # tuple

1 in t

True

5 in t

False

len(t)

4

sorted(t, reverse=True)

[4, 3, 2, 1]

sum(t)

d = {1: 'a', 2: 'b', 3: 'c', 4: 'd'} # dict

1 in d

True

5 in d

False

'a' in d

False

len(d)

4

sorted(d) # only sorts the keys

[1, 2, 3, 4]

sum(d) # applies only on keys
