Python strings

A string is a sequence of characters. Which is an array of bytes representing Unicode characters. A string character is simply a string with a length of one. The square bracket [] can be used to access elements of the string.

·    Strings in python are surrounded by either a single quotation mark or a double quotation mark.

·    Like ‘Hello python’ or “Hello python”.

print('Hello Python')

print("Hello Python")



Single-line string

·         To assign a single line string to a variable, use this:

Example

a = "Hello Python"

print(a)



Multiline string

·         To assign the multiline string to a variable, use three single quotes or three double-quotes.

Example

a = '''Lorem ipsum dolor sit amet consectetur adipisicing elit. Itaque earum eius, sapiente error quos distincti est recusandae necessitatibus provident'''

print(a)



Example

a = """Lorem ipsum dolor sit amet consectetur adipisicing elit. Itaque earum eius, sapiente error quos distincti est recusandae necessitatibus provident"""

print(a)



Note:- The line breaks are inserted at the same position.

Looping a string

·         We can loop through the characters in a string with a “for” loop.

Example

for x in "Hello":

    print(x)



String length

·         The len() function returns the length of string.

Example

a = "Hello Python"

print(len(a))
