Write a function that will return a string of country codes from an argument that is a string of prices (containing dollar amounts following the country codes).
Your function will take as an argument a string of prices like the following: "US\$40, AU\$89, JP$200".
In this example, the function would return the string "US, AU, JP".
Hint: You may want to break the original string into a list, manipulate the individual elements, then make it into a string again.
It may be helpful to look into splitting strings by a delimiter.
There's a good chance most of us have come across a .csv file, or maybe even an excel file.
A CSV or Comma Separated Value file has a , as a delimiter as follows:
119736,FL,CLAY COUNTY,498960,498960,498960,498960,498960,792148.9,0,9979.2,0,0,30.102261,-81.711777,Residential,Masonry,1The information above represents what you could think of as a single row in an excel file. Each value is it it's own "column" separated by comma. This is a common way tabular data is stored into text files which are then shared.
When someone wants to read the data into a program variable list, or some other program, they need to know what delimits the values, in the case of a csv, a comma (generally). So when someone reads a line in a csv, they know each value is separated by a comma!
