Fix: TypeError: set object is not subscriptable

We get a TypeError that the set object is not subscriptable when we try to access the elements of a set in Python like a list or a tuple.

Reason for the Error:

We cannot access elements of a set using indexing e.g. data[0] like lists or tuples.

Example of the Error:

data_set = {12, 121, 9, 14}
print(data_set[0])

Traceback:

TypeError Traceback (most recent call last)

<ipython-input-4-174921f67730> in <cell line: 2>()
      1 data_set = {12, 121, 9, 14}
----> 2 print(data_set[0])

TypeError: 'set' object is not subscriptable

Python Error - TypeError - set object is not subscriptable

How to fix the Error:

To access elements of a set in Python, you can do one of the following,

Iterate the set using for loop.

data_set = {12, 121, 9, 14}

for element in data_set:
    print(element)

Convert set to a list to access using an index:

data_set = {12, 121, 9, 14}
data_list = list(data_set)

print(data_list[0])
