String In Python

String Data Type in Python

• String is the collection of alpha numeric data, special character etc in single or double quotations.
• There are many built in method to perform operations on string,
• like to convert any string to uppercase, lowercase, to check is digit? is number?, length of string, searching in string etc.
• String is the immutable data type, that cannot be update or modify after creation

How To Create String

Examples:

str1 = “Rushikesh Jethure”

str2 = “238843” # numeric string

str3 = “Rushikesh123” # alpha numeric string

str3? =? “True” # Boolean string

Access String (Element)

We can access string element using different way

Example:

str = “Rushikesh jethure”

1) Using variable method

e.g? print(str)

2) Using array method

e.g print(str[index number])

3) Using slice method

e.g print(str[starting index, ending point])

4) Using for loop method

str = “Rushikesh jethure”

for i in str:

? print(i)

Iterate String Using For Loop

We can iterate string items using for loop to access any specific items or to check any specific item in a string at specific location (index number)

Iterate means, we can get items of sequence data type one by one.

Example:

str = “Rushikesh”

for i in str:

? print(i)

R

u

s

h

i

k

e
