Python does not support string mutation. That is to say, it does not allow any characters from a string to be deleted or updated. If we attempt to do so, it raises an error. However, the deletion of the entire string is possible with the use of the built-in del keyword. The main reason for getting an error in the case of a string update is that strings are immutable. In the following code block, let's create a string, and try to update some characters in it, as follows:

# Updation of a character

String = "Exploratory Data Analysis"

String[2] = 'p'
print("
Updating character at 2nd Index: ") 
print(String) 

The preceding code should give you an error.
