Matplotlib: Error Bar Rendering on Polar Axis
Matplotlib: Error Bar Rendering on Polar Axis
In data visualization, error bars are used to indicate the uncertainty or variability of data points. Matplotlib is a popular data visualization library in Python that provides built-in support for error bars. In this lab, we will learn how to create error bar plots in polar coordinates using Matplotlib.

Pandas DataFrame Ne Method
Pandas DataFrame Ne Method
In this tutorial, we will learn about the ne() method in pandas DataFrame. The ne() method is used to compare a DataFrame with other data structures element-wise, and it returns a DataFrame of bool values that represent the result of the comparison.

Capitalize First Letter In Words
Capitalize First Letter In Words
In Python, we can capitalize the first letter of every word in a string using a built-in function. In this challenge, you will be asked to write a function that takes a string as an argument and returns a new string with the first letter of every word capitalized.

Plotting Histograms With Matplotlib
Plotting Histograms With Matplotlib
Matplotlib is a popular data visualization library in Python. One of the most common ways to visualize data distributions is by using histograms. In this lab, we will learn how to create histograms with Matplotlib and explore different customization options.

Sum of powers
Sum of powers
In this challenge, you are required to write a Python function that calculates the sum of the powers of all the numbers from start to end (both inclusive).
Python
Key of Max Value
Key of Max Value
In Python, dictionaries are a useful data structure that allows you to store key-value pairs. Sometimes, you may need to find the key of the maximum value in a dictionary. In this challenge, you will write a function that takes a dictionary as an argument and returns the key of the maximum value in the dictionary.

A First Program
This section discusses the creation of your first program, running the interpreter, and some basic debugging.
Python
Find All Matching Indexes
Find All Matching Indexes
In this lab, you will learn how to use the `enumerate()` function and list comprehension in Python to find the indexes of all elements in a list that satisfy a given testing function.
Python
All Indexes of Value
All Indexes of Value
In Python, a list is a collection of items that are ordered and changeable. Sometimes, we need to find all the indexes of a specific value in a list. In this challenge, you will create a function that returns a list of indexes of all the occurrences of an element in a list.
Python
Mapped List Average
Mapped List Average
In this lab, we explore the use of the `map()` and `sum()` functions in Python to calculate the average of a list of elements after applying a provided mapping function to each element.
Python
Map List to Dictionary
Map List to Dictionary
In Python, a dictionary is a collection of key-value pairs. Sometimes, we need to create a dictionary from a list where the keys are the elements of the list and the values are the result of applying a function to those elements. In this challenge, you will create a function that maps the values of a list to a dictionary using a function.
Python
Efficient Prime Number Detection
Efficient Prime Number Detection
In mathematics, a prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is not prime because it is a product (2 × 2) in which both numbers are smaller than 4. In this challenge, you need to write a Python function to check if a given number is prime or not.

Split List into N Chunks
Split List into N Chunks
In Python, we can split a list into smaller lists of equal size using a simple function. This can be useful when we want to process large amounts of data in smaller chunks. In this challenge, you will be asked to write a function that takes a list and an integer n as input and returns a list of n smaller lists, each containing an equal number of elements from the original list.
Python
Find the Last Matching Index
Find the Last Matching Index
In Python, we can use a list comprehension and enumerate() to find the index of the last element in a list that satisfies a given condition. This challenge will test your ability to use these tools to solve a problem.
