  • Volunteer to help adults solve their tech problems
  • Easy service hours!
  • Mr. Bui will provide pizza
• File Reading/Writing (Input/Output) Review:
  • Python File Methods/Functions
  • Python String Methods/Functions

• Complete the File R/W (I/O) Exercises:
  1. Read a file with first and last names of people. Extract all their initials, such that first and last initials are combined per person (Paul Bui -> PB). Write/Output that list of initials to a file
  2. Write a program that generates a textfile with 10000 random numbers from 0-100
  3. 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()
