Tuesday (2/23/16)
Agenda:
- File I/O review
- Demo any missing assignments
- Benford's Law Assignment
- Create a text file that contains a list of 1000 numbers from a naturally occurring data set
- If you cannot find one, try to getting ideas from:
- Write a python program that reads the file, extracts the first digit of every number, and determines the frequencies of 0-9
- Print out the frequencies (percentages) of the numbers 0 through 9
- Create a text file that contains a list of 1000 numbers from a naturally occurring data set
Wednesday - Friday (2/17/16 - 2/19/16)
Agenda:
- Introduction to File Reading & Writing (Input & Output)
- Assume you have a single string containing the entire U.S. Constitution. Calculate and print out the frequency of the word "the"
- Download the following file: Media:Constitution.txt
- Hint: There is a useful string function that converts a string to a list of words.
- Write a program that generates a textfile with 10000 random numbers from 0-100
- Assume you have a single data file with 10000 random numbers from 0 to 100. Print out the frequency of each of the numbers.
- Assume you have a list of strings of peoples' full names in random order. Print out an alphabetized list of only the last names.
- Assume you have a single string containing the entire U.S. Constitution. Calculate and print out the frequency of the word "the"
- Example code to help read in a file:
# open a text file
file = open("Constitution.txt", "r")
# read all lines in the file and save in the constitution string variable
constitutionStr = file.read()
# close the file
file.close()
print(constitutionStr)
- Example code to help write to a file:
# open a text file
file = open("output.txt", "w")
# read all lines in the file and save in the constitution string variable
file.write("Hello!\n")
file.write("world!")
# close the file
file.close()
Wednesday - Friday (2/10/16 - 2/12/16)
Agenda:
- Complete Advanced Python List Exercises
- Benford's Law
- Read and watch Benford's Law and Fraud Detection
- Further reading Benford's Law
- Research and find a set of naturally occurring numbers. Here are some ideas, but you can come up with your own:
- Testing Benford's Law
- U.S. Government's Open Data
- U.S. Census Bureau
- Heights of mountains
- Atomic weights in the periodic table
- Baseball statistics
- etc.
- Create a text file that contains a list of your numbers (try to have a list of 1000 numbers if possible)
Monday (2/8/16)
Warmup:
- Given numList = [9, 6, 3, 1, 3, 6, 8]
- Use a for loop to print out half of each element
- Given strList = ["Arlington", "Fairfax", "Falls Church", "Alexandria"]
- Use a for loop to print out the first letter of each element
Agenda:
- CRFs & CS Courses
- Complete Advanced Python List Exercises
Thursday (2/4/16)
Warmup:
- Given the following list: warmupList = [1, 3, 5, 2, 4, 6]
- Swap the first and last elements in warmupList (you should use a temp variable)
- Be sure to make it so that your code works for ANY list (i.e. any numbers in the list)
Agenda:
- CRFs & CS Courses
- Complete Advanced Python List Exercises
