Minimal Error Example<\/h2>\n

Given the following minimal example where you create a set and attempt to access an element of this set using indexing<\/a> or sli<\/a>c<\/a>ing<\/a>:<\/p>\n

my_set = {1, 2, 3}\nmy_set[0]<\/pre>\n
If you run this code snippet, Python raises the TypeError: 'set' object is not subscriptable<\/code>:<\/p>\n
Traceback (most recent call last): File \"C:\\Users\\xcent\\Desktop\\code.py\", line 2, in <module> my_set[0]\nTypeError: 'set' object is not subscriptable<\/pre>\n
Why Does the Error Occur?<\/h2>\n
The Python TypeError: 'set' object is not subscriptable<\/code> occurs if you try to access an element of a set using indexing or slicing that imply an ordering of the set. <\/p>\n
However, sets are unordered collections of unique elements<\/em><\/strong>: they have no ordering of elements. Thus, you cannot use slicing or indexing, operations that are only possible on an ordered type.<\/p>\n

How to Fix the Error?<\/h2>\n
How to fix the TypeError: 'set' object is not subscriptable<\/code>?<\/strong><\/p>\n
To fix the TypeError: 'set' object is not subscriptable<\/code>, either convert the unordered set to an ordered list<\/a> or tuple<\/a> before accessing it or get rid of the indexing or slicing call altogether.<\/p>\n
Here’s an example where you convert<\/a> the unordered set to an ordered list first. Only then you use indexing or slicing so the error doesn’t occur anymore:<\/p>\n
my_set = {1, 2, 3} # Convert set to list:\nmy_list = list(my_set) # Indexing:\nprint(my_list[0])\n# 1 # Slicing:\nprint(my_list[:-1])\n# [1, 2]\n<\/pre>\n
Alternatively, you can also convert<\/a> the set to a tuple to avoid the TypeError: 'set' object is not subscriptable<\/code>:<\/p>\n
my_tuple = tuple(my_set)<\/pre>\n
