Strings In Python

Strings in Python:

Like many other programming languages, strings in python is also an array of bytes, that represents Unicode characters.

       However, Python doesn't have a character (char) data type. A single character is simply a string with a length of 1.

In python, we use square brackets to access the elements of strings. We can use both single and double quotes in python to define a string.

Print("strings in double-quotes")     #this will print ->  strings in double-quotes
Print('strings in single quotes')        #this will print ->  strings in single quotes

Assigning String to a variable:

Let's take an example:

str="hello world"
str1='Hey! This is a string example'
print(str)
print(str1)

---

Access elements in the string:

For accessing elements in strings, we use square brackets to access the elements.

str="Hello programmers"                #in strings in python indexing start from 0

print(str[2])                                          #here output will be "I"

                      

  

---

Multiline Strings:

In Python, you can also use three quotes for writing multiline strings.

str=''' Hello world!

         This is Multiline strings

         in python'''

print(str)

---

Slicing in Python:

In Python Strings, You can return specific characters by using slice syntax.

Syntax:

a[start:end:gap]      

a="Hello Programmers!"

print(a[2:9:2])                                 #starts wih index 2 and ends at 9 with skip 2 .

---

Negative Indexing:

We can use negative indexing to access elements from back.

a = "Hello, World!"
print(a[-5:-2])

 

---

String Length:

To get the length of a string, use the len() function.

a = "Hello, World!"
print(len(a))
