  1. Check if the columns contain Nan using .isnull() and check for empty strings using .eq(''), then join the two together using the bitwise OR operator |. Sum along axis 0 to find columns with missing data, then sum along axis 1 to the index locations for rows with missing data.

  2. NumPy (Num erical Py thon) is an open source Python library that’s widely used in science and engineering. The NumPy library contains multidimensional array data structures, such as the homogeneous, N-dimensional ndarray, and a large library of functions that operate efficiently on these data structures.

  3. There are a number of ways to assign values to a structured array: Using python tuples, using scalar values, or using other structured arrays. Assignment from Python Native Types (Tuples) # The simplest way to assign values to a structured array is using python tuples.

  4. In this step-by-step tutorial, you'll learn how to start exploring a dataset with pandas and Python. You'll learn how to access specific rows and columns to answer questions about your data. You'll also see how to handle missing values and prepare to visualize your dataset in a Jupyter notebook.

  5. You can search an array for a certain value, and return the indexes that get a match. To search an array, use the where() method.

  7. We’ll start with a quick, non-comprehensive overview of the fundamental data structures in pandas to get you started. The fundamental behavior about data types, indexing, axis labeling, and alignment apply across all of the objects. To get started, import NumPy and load pandas into your namespace: Fundamentally, data alignment is intrinsic.
