+# This program works with two CSV files. 
+# One of them contains information about some students on a course:
+
+# id;first;last
+# 12345678;peter;pythons
+# 12345687;jean;javanese
+# 12345699;alice;adder
+
+# The other contains the number of exercises each student has completed each week:
+
+# id;e1;e2;e3;e4;e5;e6;e7
+# 12345678;4;1;1;4;5;2;4
+# 12345687;3;5;3;1;5;4;6
+# 12345699;10;2;2;7;10;2;2
+
+# As you can see above, both CSV files also have a header row, which tells you what each column contains.
+
+# Please write a program which asks the user for the names of these two files, reads the files, and then prints out the total number of exercises completed by each student. 
+# If the files have the contents in the examples above, the program should print out the following:
+
+
+# Student information: students1.csv
+# Exercises completed: exercises1.csv
+# pekka peloton 21
+# jaana javanainen 27
+# liisa virtanen 35
+
+# Hint: while testing your program, you may quickly run out of patience if you always have to type in the file names at the prompt. 
+# You might want to hard-code the user input, like so:
+
+# if False:
+#     # this is never executed
+#     student_info = input("Student information: ")
+#     exercise_data = input("Exercises completed: ")
+# else:
+#     # hard-coded input
+#     student_info = "students1.csv"
+#     exercise_data = "exercises1.csv"
+	
+# The actual functionality of the program is now "hidden" in the False branch of an if statement. It will never be executed.
+
+# Now, if you want to quickly verify the program works correctly also with user input, you can just replace False with True:
+
+
+# if True:
+#     student_info = input("Student information: ")
+#     exercise_data = input("Exercises completed: ")
+# else:
+#     # now this is the False branch, and is never executed
+#     student_info = "students1.csv"
+#     exercise_data = "exercises1.csv"
+	
+# When you have verified your program works correctly, you can remove the if structure, keeping the commands asking for input.
