(i) Slice is a substring of a main string. A substring can be taken from the original string by using [ ]. operator and index or subscript values.
(ii) Thus, [ ] is also known as slicing operator.Using slice operator, you have to slice one or more substrings from a main string.
General format of slice operation :
Str [start : end]

Output : School School School

Python will not allow deleting a particular character in a string. Whereas you can remove entire string variable using del command.
Example :
>>> strl="How about you"
>>> print (str1)
How about you
>>> del str1
>>> print (str1)
Traceback (most recent call last):
File "", line 1, in
print (strl)
NameError : name 'str1' is not defined

Strings in python are immutable. That means, once you define a string moditications or deletion is not allowed. However, we can replace the existing string entirely with the new string.

(i) String is a data type in python, which is used to handle array of characters.
(ii) String is a sequence of Unicode characters that may be a combination of letters, numbers, or special symbols enclosed within single, double or even triple quotes.
(iii) Example :
Welcome to learning Python"
"Welcome to learning Python"
""Welcome to learning Python""
