Python is a popular programming language for various purposes, including web development, data analysis, machine learning, and scientific computing.
One of the main benefits of Python is its simplicity and readability. It uses indentation to define code blocks, which makes it easy to understand and write. Python also has a large standard library, meaning many common programming tasks can be performed without installing additional libraries.
There are many ways to get started with Python. You can install it on your own computer and use a text editor or integrated development environment (IDE) to write and run Python code. There are also many online platforms, such as Repl.it, that allows you to write and run Python code in a web browser.

Numpy extract() function is used for returning elements of the array if any specified condition is satisfied. The extract() function can be used by imported as import numpy as np, and we can create multidimensional arrays and derive other mathematical statistics with the help of Numpy. Numpy extract() Numpy.extract(condition, array) function returns elements of input_array … Read more
Numpy compress() is an inbuilt function that returns selected slices of an array along a given axis. The compress() function defined under NumPy, which can be imported as import NumPy as np, and we can create multidimensional arrays and derive other mathematical statistics with the help of NumPy, which is a library in Python. When … Read more
The empty_like() function is defined under NumPy, which can then be imported as import numpy as np. Numpy empty_like() function used to return an array of a similar shape and size as of the given array. np.empty_like The np.empty_like() function in Numpy is used to create the new array with the same shape and type … Read more
Python NumPy put() is an inbuilt function that is used to replace specific array elements with given values. If we want to replace any array element with another value we can use this function. Python NumPy put() Numpy put(array, indices, p_array, mode = ‘raise’) function replaces specific elements of an array with given values of … Read more
Numpy asmatrix() function that creates a matrix interpreting the given input. Unlike matrix function, it does not make a copy of the input provided is a matrix or ndarray. The numpy.asmatrix(data, dtype = None) returns a matrix by interpreting the input as a matrix. Numpy asmatrix() NumPy asmatrix() function is used to interpret a given … Read more
Pandas Dataframe.filter() is an inbuilt function that is used to subset columns or rows of DataFrame according to labels in the particular index. The DataFrame filter() returns subset the DataFrame rows or columns according to the detailed index labels. One thing to note that this routine does not filter a DataFrame on its contents. The … Read more
Pandas Dataframe.assign() method assigns new columns to a DataFrame, returning the new object (a copy) with the new columns added to the original ones. Please be careful while assigning the new columns because existing columns that are re-assigned will be overwritten. Pandas assign example To assign new columns to a DataFrame, use the Pandas assign() … Read more
Pandas dropna() is an inbuilt DataFrame function that is used to remove rows and columns with Null/None/NA values from DataFrame. Pandas dropna() method returns the new DataFrame, and the source DataFrame remains unchanged. We can create null values using None, pandas. NaT, and numpy.nan properties. Pandas dropna() Function Pandas dropna() method allows the user to … Read more
Pandas.DataFrame.rename() is a function that changes any index or column names individually with dict, or It changes all index/column names with a function. The DataFrame.rename() method is quite useful when we need to rename some selected columns because we need to specify the information only for the columns which are to be renamed. Pandas DataFrame rename … Read more
Pandas Dataframe.iloc[] function is used when an index label of the data frame is something other than the numeric series of 0, 1, 2, 3….n, or in some scenario, the user doesn’t know the index label. Rows can be extracted using the imaginary index position, which isn’t visible in the DataFrame. Pandas iloc Pandas.DataFrame.iloc is … Read more
