#John Bible 11/1/21 #What I learned was how to use curl read and open. #What I had problems with was task 4 because I mixed up my for and while loops but I fixed it by changing the loop I was using.

# [ ] review and run example !curl https://raw.githubusercontent.com/MicrosoftLearning/intropython/master/poem1.txt -o poem1.txt

# [ ]Run to open the file in memory as poem_file poem_file = open('poem1.txt', 'r')

# [ ] run and review code to test if open worked # should display name='poem1.txt' and no errors poem_file

# [ ] import cities.txt #This will import cities.txt !curl https://raw.githubusercontent.com/MicrosoftLearning/intropython/master/cities -o cities.txt

# [ ] open cities.txt as cities_file # [ ] test cities.txt was opened #This will open cities.txt as cities_file and then test that cities.txt was opened cities_file = open('cities.txt', 'r') cities_file

# [ ] review and run example poem_contents = poem_file.read()

# [ ] review and run example # shows the file as a string with formatting characters such as "\n", output should be non-blank poem_contents

# [ ] review and run example # since .read() loaded the file as a string it can be printed print(poem_contents)

# [ ] after import and open of cities.txt in task 1 # [ ] read cities_file as cities # [ ] display the string: cities #This will read cities_file as cities and display the string cities=cities_file.read() cities

# [ ] print the string: cities #This will print the string print(cities)

# [ ] review and run example to read poem1.txt 10 characters at a time poem_file = open('poem1.txt', 'r') poem_10char = poem_file.read(10) print(poem_10char) poem_10char

# [ ] review and run example, + 10 more characters # reads and displays without storing in a variable poem_file.read(10)

# [ ] review and run example, + 10 more characters # reads and stores in variable poem_parts poem_parts = poem_file.read(10) print(poem_parts)

# [ ] REPEATEDLY RUN this cell, + 5 more characters each time run are appended using string addition # [ ] consider why no additional text displays after multiple runs poem_parts += poem_file.read(5) print(poem_parts)

# [ ] digits of pi # 1. import digits_of_pi.txt #This will import digits_of_pi.txt !curl https://raw.githubusercontent.com/MicrosoftLearning/intropython/master/digits_of_pi -o digits_of_pi.txt

# [ ] digits of pi # 2. open as digits_of_pi_text # 3. read() 4 char of digits_of_pi_text to pi_digits variable # 4. print pi_digits #This will read and then print the first 4 digits digits_of_pi_text = open("digits_of_pi.txt","r") pi_digits=digits_of_pi_text.read(4) print(pi_digits)

# [ ] digits of pi # 5. add to pi_digits string with string addition # a. add next 4 characters from digits_of_pi obtained from read() # b. run the cell multiple times to get more digits of *pi* #This will add 4 digits to pi_digits everytime this cell is ran pi_digits += digits_of_pi_text.read(4) print(pi_digits)

# [ ] review and run example poem_file = open('poem1.txt', 'r') poem_part = poem_file.read(15).upper() print(poem_part)

# [ ] review and run example poem_part = poem_file.read(6).title() print(poem_part)

# [ ] review and run example poem_part = poem_file.read(6) print(poem_part) print(poem_part.isalpha(), "isalpha() because of `\\n`") poem_part

# [ ] review and run example poem_file = open('poem1.txt', 'r') poem_text = poem_file.read() print(poem_text[8:26])

# [ ] complete the task #This will iterate through the characters testing for .isupper() for initials_c and looking for \n for initials cities_file=open("cities.txt","r") cities=cities_file.read() initials_c=[] initials=[] for digit in cities: if digit.isupper(): initials_c.append(digit) elif digit is "\n": initials.append(digit) print("initials_c:",initials_c) print("initials:",initials)
