machine learning with python -machine datalearning loading for ml projects suppose if you want to start ml project then what is the first and most important thing you would requireit is the data that we need to load for starting any of the ml project with respect to datathe most common format of data for ml projects is csv (commaseparated valuesbasicallycsv is simple file format which is used to store tabular data (number and textsuch as spreadsheet in plain text in pythonwe can load csv data into with different ways but before loading csv data we must have to take care about some considerations consideration while loading csv data csv data format is the most common format for ml databut we need to take care about following major considerations while loading the same into our ml projectsfile header in csv data filesthe header contains the information for each field we must use the same delimiter for the header file and for data file because it is the header file that specifies how should data fields be interpreted the following are the two cases related to csv file header which must be consideredcase-iwhen data file is having file headerit will automatically assign the names to each column of data if data file is having file header case-iiwhen data file is not having file headerwe need to assign the names to each column of data manually if data file is not having file header in both the caseswe must need to specify explicitly weather our csv file contains header or not comments comments in any data file are having their significance in csv data filecomments are indicated by hash (#at the start of the line we need to consider comments while loading csv data into ml projects because if we are having comments in the file then we may need to indicatedepends upon the method we choose for loadingwhether to expect those comments or not delimiter in csv data filescomma (,character is the standard delimiter the role of delimiter is to separate the values in the fields it is important to consider the role of delimiter while uploading the csv file into ml projects because we can also use different delimiter such as tab or white space but in the case of using different delimiter than standard onewe must have to specify it explicitly
