- File Reading/Writing (Input/Output) Review:
- Complete the File R/W (I/O) Exercises:
- Read a file with first and last names of people. Print out a list of all their initials. Output that list of initials to a file
- Write a program that generates a textfile with 10000 random numbers from 0-100

Monday - Tuesday (2/27/17 - 2/28/17)
Agenda:
- Teen Tech Help @ Central Library, Thursday (3/9/17), 3:30-5pm
- Volunteer to help adults solve their tech problems
- Easy service hours!
- Mr. Bui will provide pizza
- File Reading/Writing (Input/Output) Review:
- Complete the File R/W (I/O) Exercises:
- Read a file with first and last names of people. Print out a list of all their initials. Output that list of initials to a file
- Write a program that generates a textfile with 10000 random numbers from 0-100
- Read a file with 10000 random numbers from 0 to 100. Print out the frequency of each of the numbers (Hint: Use a list to track the frequencies)
- 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()
# read all lines from the file and save them to a listlist
constitutionList = file.readlines()
# close the file
file.close()
print(constitutionStr) # What does it print? Comment this line out and uncomment the next line
#print(constitutionList)
- 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()
