If you know your way around a spreadsheet, you can think of an array as a one-column spreadsheet. The name of the column is the name of the array itself. Likewise, the row number is the index of an array element. You just need to keep in mind that an array index starts at0and n...
43. Make an array immutable (read-only) 44. Consider a random 10x2 matrix representing cartesian coordinates, convert them to polar coordinates 45. Create random vector of size 10 and replace the maximum value by 0 46. Create a structured array with x and y coordinates covering the [0,1]...

In this article, we will study what is an array in python programming and how to initialize an array in python? We will understand different methods to do it. Also, we will see an example of each method along with its syntax to be followed and the output of the example given. So let...
