To begin, let’s create a simple DataFrame with 5 fruits (all in uppercase) and their prices: As you can see, all the 5 fruits are captured in uppercase: Next, change the strings to lowercase using this template: So the complete Python code would look as follows: Run the code, and you’ll notice that the 5 fruits are now in lower case: What if each value in the DataFrame contains multiple words in uppercase? ... will use the DataFrame displayed in the above example to explain how we can convert the data type of column values of a DataFrame to the string.
