This tutorial is fully made for intermediate and absolute beginners.
you can learn from the very beginning so let's take a look. there is some statement like print, input or many so can learn it by doing code yourself, if there is something important so I can highlight it, so don't need to worry about it.
String :
"String is type of alphabetic code like english letters"
In python you can define string as ::
a=3
b="String"
print(a,b)
print("my name is",(a))
print("This is ",str(b))
The string is a very easy topic and you can learn it is very fast and also python is very simple so don't panic that how can I learn this.
String Slicing:
Slicing is a way to find a substring from the main string with some specific location.
before slicing you must know about the indexes because in any language we'll count from 0.
so like in the name "NITIN" there is 5 number then indexing is ::
N I T I N
0 1 2 3 4
now syntax is : : print(string_name[starting_index: ending_index])
first_String= "NITIN"
print(first_String[0:2])
OUTPUT : NI
It'll print n-1 number, n= end_index.
print(name[-4:-1]) # It's same as name[1:4]
OUTPUT : ITI
It'll start printing from at index 1.
for more detail :
name="nitin"
# concatenating two strings
print(name[3])
name[2]="v" # it dose not work
print(name[0:4])#it's called string slicing
print(name[:3])#it's automatically detect first string which is [0]
print(name[0:]) #it's automatically detect last string which is [4] in case of nitin
print(name[-4:-1])# It's same as name[1:4]
print(name[1:4:2])
OUTPUT :
i
niti
nit
nitin
iti
ii
String Function :
story="my name is nitin singh rawat is is isis is is is"
#string functions
print(len(story)) # It's print the length of string.
print( story. endswith("rawat")) # It'll give you a boolean T\F. If string ends with
the given value or not.
print(story.count("my")) #It'll count the strings.
print(story.capitalize()) # It'll capitalize first later of your strings.
print(story.find("is")) # It'll find if value with the help of indexes it also count
white spaces.
print(story.replace("is","isa")) # It'llreplace the strings.
story="nitin is good boy, \n he's pursuing \\ b.tech cse " #escape sequences
print(story)
OUTPUT :
48
False
1
My name is nitin singh rawat is is isis is is is
8
my name isa nitin singh rawat isa isa isaisa isa isa isa
nitin is good boy,
he's pursuing \ b.tech cse
