Thursday - Friday (2/23/17 - 2/24/17)
- 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
- Read a file with 10000 random numbers from 0 to 100. Print out the frequency of each of the numbers.
- Read a file with first and last names of people. Print out a list of all their initials
- 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()
# 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()
