As we indicated earlier, we need to convert the numbers to strings. Definition and Usage. While programming we have to write a lot of data to be stored in the computer except the data structure list object in memory to perform a further operation or store it for later use. In this example, I have imported a module called numpy as np and taken a variable as rows. the values in the list are of different types -- float,int, strings.How do I write it into a csv file so that my output csv file looks like 1.2,abc,3 1.2,werew,4 . Lists are equivalent to C or Pascal arrays in their time complexity; the primary difference is that a Python list can contain objects of many different types. Example.
