Python error "TypeError: string indices must be integers, not str"

My friend who has a little bit knowledge about machine learning was getting the following python error:

 File "em_sep.py", line 13, in <module>

    if ema_1["confidence_score"] == "50":

TypeError: string indices must be integers, not str

Line 13 of the the code:

email_s.append(email_1["email_address"])

TypeError: string indices must be integers, not str

TypeError: means that you are trying to perform an operation on a value whose type is not compatible with that operation. An Iterable is a collection of elements that can be accessed sequentially . In Python, iterable objects are indexed using numbers . When you try to access an iterable object using a string or a float as the index, an error will be returned as TypeError: string indices must be integers. This means that when you’re accessing an iterable object like a string or float value, you must do it using an integer value.

For example, str[hello"] and str[2.1] as indexes. As these are not integers, a TypeError exception is raised. This means that when you’re accessing an iterable object like a string or float value, you must do it using an integer value . If you are accessing items from a dictionary , make sure that you are accessing the dictionary itself and not a key in the dictionary.

Python supports slice notation for any sequential data type like lists, strings , tuples, bytes, bytearrays, and ranges. When working with strings and slice notation, it can happen that a TypeError: string indices must be integers is raised, pointing out that the indices must be integers, even if they obviously are.
