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

# [ ] open cities.txt as cities_file # [ ] test 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 !curl https://raw.githubusercontent.com/MicrosoftLearning/intropython/master/cities -o cities.txt cities_file = open('cities.txt', 'r') cities = cities_file.read() cities

# [ ] print the string: cities 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 !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 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* 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 cities_file = open('cities.txt','r') cities = cities_file.read() initials="" print(cities) for Mcity in cities: if Mcity.isupper() == True: initials += Mcity elif Mcity == "\n": initials += Mcity else: pass print(initials)
