title: Read csv file by column number in pandas python
body: <p>I have a csv file with hundreds of columns, each column with long names. Is there a way to read only the specified columns by number like column number 2 to 5 and column number 50 to 71. I know I can read specified columns by the column names using the 'usecols' parameter but can I specify the column numbers to get the desired columns?</p>
