Q$3$: Read in data$/$hip$\_$small.csv and write out a file data$/$hip$\_$bright.csv where you only write out the lines where $V($mag$)$ column is less

than $5.$ Be sure to remove headers and blank lines.

In $[2]$: infile $=$ open$(\text{'}$data$/$hip$\_$small.csv$\text{'},\text{'}$r$\text{'})$

for line in infile:

if line.startswith$("$#$")$ or line.isspace$()$:

continue

outfile $=$ open $(\text{'}$data$/$hip$\_$bright.csv$\text{'},\text{'}$w$\text{'})$

llist $=$ line.split $(\text{'},\text{'})$

infile.close$()$
