In Python, strings are immutable, and lists are mutable. Hence, we can sort the string by converting it into a list first. We will then use a sorting algorithm (insertion sort or bubble sort) to sort the converted list. Finally, we will convert the sorted list to a string and print ...
Python Copy word[42:] The output is:Output Copy '' String immutabilityPython strings are immutable, which means they can't be changed. Assigning a value to an indexed position in a string therefore results in an error:Python Copy

has the same memory position. With this you don't waste memory declaring the same object multiple times. Because of a string is defined in many places if there was mutable a change to one will cause a change in the others, and no ones want that. That's why the strings...
A Python String object is immutable, so you can’t change its value. Any method that manipulates a string value returns a new String object. The examples in this tutorial use thePython interactive consolein the command line to demonstrate different methods that remove characters. ...

Thus, Strings are immutable, or unchangeable. Note Some String methods (such as public String toUpperCase(Locale l)) appear to modify a String, but in actuality, don’t. Instead, such methods create a new String containing a modified string. String method sampler String contai...
