Printing the list has been dealt many times. But sometimes we need a different format to get the output of list. This also has application in getting a transpose of matrix. Printing list vertically also has application in web development. Lets discuss certain ways in which this task can be achieved....
Suppose we have a function and we want to compute this function for different values in a single line of code . This is where map() function plays its role ! map() function returns a map object(which is an iterator) of the results after applying the given function to each item of a given iterable (list, tuple etc.)...
We have the task of writing memory-efficient Python list creation in the case of Generators and printing the result. In this article, we will demonstrate memory-efficient Python list creation using Generators....
We have a problem statement of how to minimize script execution time in Python. Minimizing the Python Script execution becomes very crucial for getting better and optimized output for an application in production or when we are doing CP or DSA. In this article, we will see how to minimize script execution time using different methods and approaches....
Lists are just like arrays, declared in other languages. Lists need not be homogeneous always which makes it the most powerful tool in Python. A single list may contain data types like Integers, Strings, as well as Objects. Lists are mutable, and hence, they can be altered even after their creation....
Here, we will understand the difference between Python List and Python Numpy array....
In Python, a += b doesn’t always behave the same way as a = a + b, the same operands may give different results under different conditions. But to understand why they show different behaviors you have to deep dive into the working of variables. before that, we will try to understand the difference between Python Variable and List Reference in Python....
This is one of the most essential operation that programmer quite often comes in terms with. Be it development or competitive programming, this utility is quite essential to master as it helps to perform many tasks that involve this task to be its subtask. Lets discuss various approaches to achieve this operation. Method #1 : Naive method As the brute force method, we just count all the elements and then just return the element whole count remains the maximum at the end. This is the basic method that one could think of executing when faced with this issue....
The usual append method adds the new element in the original sequence and does not return any value. But sometimes we require to have a new list each time we add a new element to the list. This kind of problem is common in web development. Let’s discuss certain ways in which this task can be performed. Method #1 : Using + operator This task can be performed if we make a single element list and concatenate original list with this newly made single element list....
Comprehensions in Python provide us with a short and concise way to construct new sequences (such as lists, sets, dictionaries, etc.) using previously defined sequences. Python supports the following 4 types of comprehension:...
In this article, we will discuss how to append the dictionary to the list data structure in Python....
