I need to rewrite this program so that it reads strings from a $.$txt file and builds the list courses instead of defining all the data as part of your program itself. The text file is called courses.txt$$The file aspect should be the only thing that you change $-$ the rest of the program logic should remain the same.$$

#table $1$

print$("$Table $1")$

total $=0$

for course in courses:

data $=$ course.split$()$

length $=$ len$($data$)$

print$($data$[0]+""+$ data$[1])$

total $+=$ int$($data$[$length$-1])$

print$("$

total: $",$ total$)$

#table$2$

print$("$Table $2")$

for course in courses:

dept$\_$code $=$ course$[$:$2]$
