Here, we will write a Python program where we will find the length of the list. We will see different ways to perform the task.
Luckily, getting the last item of a list isn’t too bad.In short, there are four ways to get the last item of a list in Python. First, you can use the length of the list to calculate the index of the last item (i.e.
Python program to get the index of ith item in pandas.Series or pandas.DataFrame # Importing pandas packageimportpandasaspd# Importing numpy packageimportnumpyasnp# Creating a dictionaryd={'a':['Raman','Bahar','Saumya','Vivek','Prashant'],'b':[20,21,22,21,20] }# Creating...
Use the Length Command to Find the Length of the List and Print it Indexing in Python Lists In a Python list, each item can be accessed by its index number. Python, like other modern-day languages, is azero-indexed languagei.e., it will start its count from zero (not 1). So, a ...
Python List Index Finding With theforLoop Method To find the index of an element in the list in Python, we can also use theforloop method. The code is: consonants=["b","f","g","h","j","k"]check="j"position=-1foriinrange(len(consonants)):ifconsonants[i]==check:position=ibrea...
The IndexError in Python occurs when an item from a list is attempted to be accessed that is outside the index range of the list.
Example 1: Get the Position of an Element Using the “index()” Method from the Python List The “index()” method integrated into Python provides a basic and straightforward technique to discover the location of an element in a list. If the element exists, it delivers the index of its ...
Get the Last Element of a List With -1 Index in PythonIf we do not want to remove the last element from the list, we have to use -1 as the list index. In Python, the -1 index means the last index. Similarly, the -2 index indicates the second last index and so on. The ...
To select an item from a list in Python, you can use indexing. Lists in Python are zero-indexed, meaning the first item has an index of 0. For example, given a listcities = ["New York", "Los Angeles", "Chicago", "Houston", "Phoenix"], you can access the first city withcities...
5.Using afor loopwith a range, we print each item from the list, using Python’s string formatting method to drop the item into the sentence as a string.How do we know the number of items in a list to create a range? Well right now it doesn’t matter as the len() function will...
