Question $2$: The cSV module

In this problem we will use the CSV module to extract information from a file containing a list of the $1,000$

largest cities in the world. Loading the file into a spreadsheet program $($like Excel$)$ we can see the first few

rows of the table:

The first line of the file is the header line $--$ we will skip that line when processing the file. The columns of

the table are the city's name, its lat$/$Ing coordinates, its country, and population.

Our task is a little bit strange. We are given an integer $x$ and we must find the number of cities whose

population is a multiple of $x.$ That is$,$ for whom the poulation mod $x$ equals zero. With $x=8($spoiler alert!$)$

the result turns out to be $315.$ That is$,315$ out of the $1,000$ largest cities have a population that is a multiple

of $8.$ Tokyo is one of them, since $37,732,000/8$ is a whole number.

Implement this in a function called population$\_$is$\_$multiple$\_$of that takes $x$ as input, and returns an

integer.

Hint

Use

to skip the header line.

def population$\_$is$\_$multiple$\_$of $(x)$ :

inputfile $=$ Path. $)/\text{'}$resources $\text{'}/\text{'}1000$cities.csv$\text{'}$

num$\_$cities $=0,$ # counter for cities with population that is multiple of $x$

with open$($inputfile$,...)$ as $f$ :

$...$ # write code to iterate through the file,

#

return num$\_$cities

$[7]$: # Use this to check your result. You should get $315$

population$\_$is$\_$multiple$\_$of $(8)$
