How do you print a list of odd index numbers in Python?

One way is using the range() function, such that it starts at the first odd index, 1 , and has a step value of 2 , so that it returns the odd indices 1, 3, 5, . Another way to obtain the odd indices of a list is using list comprehension, in which you can use a condition that will only include the odd indices.

How do you print the odd index of a string in Python?

For printing odd characters, we need to start with characters starting at position 1 with a difference of 2. Slicing operator in this case will be written as str[1::2] . index is initialized to 0. A while loop iterates over the string starting from 0 till the length of string which is calculated using len function.

How do you find the even and odd index in Python?

How to index an list to show even and odd elements in python?

1. +2.
2. +3.
3. +4. You can use a for loop to iterate on a list and you get in each iteration one element.
4. +4. lst = [your_list] odds = lst[1::2] evens = lst[0::2]

How do you print odd elements in an array?

Q. Program to print the sum of all the elements of an array.

1. Declare and initialize an array.
2. The variable sum will be used to calculate the sum of the elements. Initialize it to 0.
3. Loop through the array and add each element of array to variable sum as sum = sum + arr[i].

How do I remove odd indexed elements from a list in Python?

To remove all odds do: iter_lst = iter(lst); next(iter_lst); for x in iter_lst: lst. remove(x) .

How do you extract even and odd numbers in a list?

Algorithm to extract even and odd number from the given list

1. Take the input in the form of a list.
2. Create two empty lists to store the even and odd number which will be extracted from the given list.
3. Check each element of the given list.
4. Print both lists which will be our required list.

How do I print even elements in a list?

Python program to print even numbers in a list

1. Approach 1 − Using enhanced for loop. Example. list1 = [11,23,45,23,64,22,11,24] # iteration for num in list1: # check if num \% 2 == 0: print(num, end = ” “)
2. Approach 2 − Using filter & lambda function. Example.
3. Approach 3 − Using list comprehension. Example.

How do you print an even string in Python?

Approach: Split the string using split() function. Iterate in the words of a string using for loop. Calculate the length of the word using len() function. If the length is even, then print the word.

How do you find odd elements in a list?

Use list indexing to get elements of a list in odd positions. Use list indexing a_list[1::2] to return every other element of a_list , starting at index 1 .

How do you find the odd index?

Approach :

1. Start from the left and keep two index one for even position and other for odd positions.
2. Traverse these index from left.
3. At even position there should be even number and at odd positions, there should be odd number.
4. Whenever there is mismatch , we swap the values at odd and even index.

How do I print an array list?

These are the top three ways to print an ArrayList in Java:

1. Using a for loop.
2. Using a println command.
3. Using the toString() implementation.

How to print all odd numbers in a list in Python?

Given a list of numbers, write a Python program to print all odd numbers in given list. Example: Using for loop : Iterate each element in the list using for loop and check if num \% 2 != 0. If the condition satisfies, then only print the number.

How do I print all the odd index elements of a list?

Iterate through the list from the starting index and print the element whenever the index is odd . Another approach is that the incremented value of the index should be by 2 i.e index=index+2 where index starts from 1. This code prints all the odd index elements of a list. What platform should I use to build a site together with my team?

How do you enumerate a list in Python?

In Python, you use enumerate (): fruit = [ ‘banana’, ‘apple’, ‘pear’, ‘peach’ ] for i, item in enumerate (fruit, 1): print (i, ‘. ‘ + item, sep= ”, end = ”) How enumerate () Works The enumerate (iterable, start) function will return a sequence of tuples.

Is it possible to delete items from a list in Python?

However, you should be aware that deletion from a list is an expensive operation, proportional to the length of the list, because Python lists are implemented as dynamic arrays. ‘pop’ (removal from the end of the list) is cheap; removing from other positions will cause all elements after the removed elements to be moved.
