String indices must be integers

If you try to access values from a dictionary or iterable object using the string value instead of the integer value then you will receive the following error message:.

The Python "TypeError: string indices must be integers" occurs when we use a non-integer value to access a string at an index. To solve the error, make sure to use an integer, e. If you have an integer that is wrapped in a string, use the int class to convert it. We used the int class to convert the string to an integer to be able to access the original string at an index. The error also occurs when you use string slicing incorrectly and separate the indices by a comma instead of a colon. The start index is inclusive, whereas the stop index is exclusive up to, but not including.

String indices must be integers

All the characters of a string have a unique index. This index specifies the position of each character of the string as well. However, you have to remember that all the indexes are integers. When you specify a string or a float as the index, you will encounter an error called TypeError: String Indices Must be Integers. When we initializing a string, it starts indexing each character of the string. Here we did not encounter any error because the string indices are provided an integer value instead of a string. But we know that the string indices only accepts integer value. Thus no error is encountered. Since string indices only accept integer value. In conclusion, string indices must be integers. Moreover, if you are accessing items from a dictionary, make sure that you are accessing the dictionary itself and not a key in the dictionary. So if you encounter the TypeError, check the type of indices that you have already mentioned. Above all, always make sure that the first index and the rest are integers.

An error occurred.

To understand how to fix a TypeError in Python , you first need to know what an iterable object is. An iterable is an object that returns one of its members at a time, allowing it to be iterated over in a for loop. In Python, iterable objects are indexed or placed in data structures such as a string or dictionary using numbers, i. When values at index are extracted using string value, an incorrect type of input, it raises an error like this:. This article will explore when and how that error occurs, and how to resolve it by understanding the anatomy of certain data structures via different scenarios. Each problem instance will be understood in depth, the meaning will be interpreted and eventually will be solved.

In this article, you'll see why this error occurs and how to fix it. Why TypeError: string indices must be integers. StackOverflow for a faster and better support. But there are cases where you'll get an error that says, "TypeError: string indices must be integers" when trying to access a character in a string. Forum Donate. How to Access Values from a Dictionary in Python Let's modify our earlier example to create a dictionary of instruments and quantities. In our example, we used a comma when separating the start and end parameters: [0,6]. The error in the code is very easy to miss because we used integers — but we still get an error. Another way to extract a part of text from string is via slicing. You can use the search field on my Home Page to filter through all of my articles. When you specify a string or a float as the index, you will encounter an error called TypeError: String Indices Must be Integers. News Events Blogs Market insight. Since we were slicing the string using a comma, we received a type error because Python evaluates commas , as Tuple.

Explore your training options in 10 minutes Get Started. In Python, iterable objects are indexed using numbers. When you try to access an iterable object using a string value, an error will be returned.

All projects. By Industry. This is why we got an error. We get the "TypeError: string indices must be integers" error when we use the slice syntax incorrectly. Try watching this video on www. The wrong argument passed to search the available content in the iterable,strings and dictionaries, raised the error. Try it yourself to extract items at different locations of iterable by passing values from zero to eight. Each problem instance will be understood in depth, the meaning will be interpreted and eventually will be solved. The dict. When we initializing a string, it starts indexing each character of the string. Python supports slice notation for any sequential data type like lists, strings , tuples, bytes, bytearrays, and ranges. How to Fix the TypeError: string indices must be integers Error in Strings in Python As we saw in last section, to access a character in a string, you use the character's index.
