negative indexing in python

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

#Get the characters:
#From: "o" in "World!" (position -5)
#To, but not included: "d" in "World!" (position -2):
#b = "Hello, World!"

negative index in Python list

# Negative indexing in lists
my_list = ['p','r','o','b','e']

# last item
print(my_list[-1])
#e
# fifth last item
print(my_list[-5])
#p

python negative indexing

myList = [1, 2, 3, 4, 5]

# NORMAL INDEXING
print(myList[0]) # 1
print(myList[1]) # 2
print(myList[2]) # 3

# NEGATIVE INDEXING (STARTS FROM LAST ELEMENT IN LIST)
print(myList[-1]) # 5
print(myList[-2]) # 4
print(myList[-3]) # 3

print(myList[-3:]) # Last 3 elements

python negative indexing

list = ["Python", "Java", "C++", "Javascript", "SQL", "PHP"]
print(list[-1]) # "PHP"
print(list[-4]) # "C++"
print(list[:-3]) # ["Python", "Java", "C++"]
print(list[-2:]) # ["Javascript", "SQL", "PHP"]
print(list[-5:-2]) # ["Java", "C++", "Javascript"]

negative indexing in python

thislist = ["apple", "banana", "cherry", "orange", "kiwi", "melon", "mango"]
print(thislist[-2:])

# ["melon","mango"]

Python Negative Indexing

# Negative indexing for accessing tuple elements
my_tuple = ('p', 'e', 'r', 'm', 'i', 't')

# Output: 't'
print(my_tuple[-1])

# Output: 'p'
print(my_tuple[-6])

negative indexing in Python

# Negative indexing is does not exist in C#, Java and the like

my_list = [1, 2, 3]
print(my_list[-1])

# Output - 3

negative index python

# Negative indexes python in lists!

# Hey everybody! Looking how to do negative indexes?
# LET'S GET INTO IT!

# Have a list first, let's say your favorite colors! 
# (Mine in this case don't know about you)

fav_color = ["Blue", "White", "Grey", "Black", "Orange", "Red", 
            "Teal", "Cyan", "Green"]

# Woah so many favorite colors! I have many but I can't add too much

"""
Anyway, let's say we wanted to print the 
last item but we don't know the last index
is. (The length is 9, and the last index is 8)

We can use negative indexes! Let's write the
print function first. Inside the parentheses,
we mention a specific fav_color index.

Like this:

print(fav_color[])

Inside the brackets, we'll add a dash (-) aka
the subtraction symbol in Mathematics. Since we
want to mention the string "Green", we'll add the
integer 1 like this:

[-1]

The full syntax below:
"""

print(fav_color[-1])

# Green probably printed out: right?

"""Now you go try this yourself, print
the "Teal" index. (the third to the last
index). Here's the answer:"""

print(fav_color[-3])
