            or

X = 'some string'

print(x)

Getting character at a specified position

X = "some string"

Y = X[0]  #position in big brackets 1 st character is treated as 0th position

print(Y)

For getting character from back we have to mention -ve sign

z = X[-1]

print(z)

Getting a set of character from string

For getting a set of  a character from index a to index b we have to use

X= "some string"

Y = X[a:b] #b will be excluded

Y = X[5:8]

Getting length of string

X = "some string"

Y = len(X)

print(y)

Converting text into lower case or upper case

using x.lower()

X = "SOME string"

y=x.lower()

print(y)

Using x.upper

X = "some string"

Y = x.upper

Using strip

X = "   some string  "

Y= x.strip()

print(Y)

Can you convert "hello world" into "helloworld" using replace

Spliting a string into substring

Using x.split()

Using split a string is converted into sub-string when a specified character is reached

X = "split, me"

Y = X.split(",")

print(Y)

Taking input from user

X = input()

note that input will take a string for taking integer input we have to use casting read about casting here

Y = int(X) #for getting integer input
