Python Files Assignment Help

Question

I need help creating a code that meets the following requirements:

1. Prompt the user to enter a file name/path to read
2. Use open(filename) to open and read the file specified by the user (in the variable, filename). Read each line of the file and interpret each line as follows:
3. Ignore blank lines
4. If the line begins with the text name followed by a space, then add the remained of the line's text to a list (initially empty) of names
5. If the ling begins with the text food followed by a space, then add the remained of the line's text to a list (initially empty) of foods
6. After processing the full contents of the file (every line) print each name from the names list along with a randomly selected item from the foods list. No two names should be printed with the same food. (Hint: each time you select a random food, remove it from the foods list so that it cannot possibly be selected again)
7. For each line printed in the requirement above (a name with a random, unique food) also write the same line out to a file named output.txt. Remember that the print function automatically starts a new line, but the write function of a file does not, so you'll need to include /n

Answer 1

I do not have a python compiler..

I use the online compiler which does NOT allow me to read files on the disk...

Nevertheless, here are some code blocks to get you started..

print("Hello World")

#---------------------------------

# allegedly opening and reading the file

"""

filename = input("Filename ??? :>")

file_obj = open(filename,"r")

inbuff = file_obj.read(255)

print(inbuff)

file_obj.close()

"""

#---------------------------------

#

#use len(str)==0 to check for blank line

#

# this next block of code populates the NAME and FOOD lists

listInput = ["name Patrick","name Franny","food fruit","food vegetables"]

listName = []

listFood = []

N=len(listInput)

print(N)

for iLoop in range(int(N)):

strInbuff = listInput[iLoop]

tokens = strInbuff.split()

if tokens[0]=="name":

listName.append(tokens[1])

if tokens[0]=="food":

listFood.append(tokens[1])

print(listName)

print(listFood)

"""

# MUST have the same # of FOOD as NAMEs in the file_obj

#Finally, the next code block generates random integers

"""

from random import seed

from random import randint

# seed random number generator

seed(1)

# generate some integers

for _ in range(10):

value = randint(0, 10)

print(value)

Answer 2

# Get file path/name

file_path = input("Please enter file path")

# Open file in read mode

with open(file_path, "r") as f:

# For each line in the file

for line in f.readlines():

pass

This is just the start. Please schedule a lesson for the rest!
