how to slice string in python code example

Example 1: python string indexing

str = 'codegrepper'
# str[start:end:step]
#by default: start = 0, end = len(str), step = 1
print(str[:]) 		#codegrepper
print(str[::]) 		#codegrepper
print(str[5:]) 		#repper
print(str[:8]) 		#codegrep
print(str[::2]) 	#cdgepr
print(str[2:8]) 	#degrep
print(str[2:8:2]) 	#dge
#step < 0 : reverse
print(str[::-1]) 	#reppergedoc
print(str[::-3]) 	#rpgo
# str[start:end:-1]	means start from the end, go backward and stop at start
print(str[8:3:-1]) 	#pperg

Example 2: python slice string

name = "dx4iot"
print(name[0:]) #output: dx4iot
print(name[0:3]) #output: dx4
#==== reverse a string ====#
print(name[::-1]) #output: toi4xd
print(name[0:6:2]) #output: d4o
print(name[-4:-1]) #output: 4io

Example 3: get a slice of string in python

string = "something"

slice = string[0:3] # will be "som"
slice = string[0:-3] # will be "someth"
slice = string[3:] # will be "thing"
slice = string[:3] # same as first slice
slice = string[::2] # will be "smtig" -- it goes 2 step each time

Example 4: python string slicing

my_string = "Hey, This is a sample text"
print(my_string[2:]) #prints y, This is a sample text
print(my_string[2:7]) #prints y, Th excluding the last index
print(my_string[2::2]) #prints y hsi  apetx
print(my_string[::-1]) #reverses the string => txet elpmas a si sihT ,yeH

Example 5: how to slice a string in python

a = 'hello'
print(a[1:2])

Example 6: Python - Slicing Strings

b = "Hello, World!"
print(b[2:5])
