Assuming that the parameter text is a string, the line for letter in text[1]: doesn't make much sense to me since text[1] is a single character. What's the point of iterating over a one-letter string? However, if text is a list of strings, then your function doesn't throw any exceptions, it simply returns the string that results from replacing in the first string (text[0]) all the letters of ...

Strings are immutable objects, meaning they can't be modified in place (you'd have to return a new string and reassign it). s[i] = dict[a + 26] is trying to reassign a value in the string. Here is an easier to see example. >>> astring = "Hello". >>> astring[0] = "a". Traceback (most recent call last): File "<pyshell#1>", line 1, in <module ...

We accessed the first nested array (index 0) and then updated the value of the first item in the nested array.. Python indexes are zero-based, so the first item in a list has an index of 0, and the last item has an index of -1 or len(a_list) - 1. # Checking what type a variable stores The Python "TypeError: 'float' object does not support item assignment" is caused when we try to mutate the ...

You cannot change the character at the index position 0 because strings are immutable. You should check to see if there are any string methods that you can use to create a modified copy of a string if applicable.

greet[0] = 'J'. TypeError: 'str' object does not support item assignment. To fix this error, you can create a new string with the desired modifications, instead of trying to modify the original string. This can be done by calling the replace () method from the string.

By deftly carving out a new string that blends the old and the new, we circumvent the immutability blockade. 2. The mutable metamorphosis. Should your ambitions entail more profound transformations, it might be prudent to transform the string into a mutable entity, a list, for the interim.

An str acts like a sequence type (you can iterate over it), but strings in Python are immutable, so you can't assign new values to any of the indices.. I expect what's happening here is that you're trying to run this when req_appliances is a str object.. I came up with two ways to fix this: First, just check if it's a str before you iterate over it:. if isinstance(req_appliances, basestring ...
