Question

using python 3, I ALWAYS RATE MY ANSWERS. tHANKS

Copy princess.txt from my 153 public folder on smaug to your folder that contains myfunctions.py

1.Construct a list of all punctuation characters (use the string module classification set)

2.Use a list method to remove the apostrophe character (') from the above list

3.Prompt the user to enter the name of a file to read

4.For each line in the file

5.Use string methods to make it all lower case and remove any leading or trailing white space

6.Call your replace_chars function with the modified line (from step 5) and the list from step 2

7.Display the modified line (from step 6) preceded by the line number. Use the string format method in this step.

Here is princess.txt

Mother|{Enters.} Hi, honey.
Grandson|Hi, Mom.

Grandson|A little bit.

Grandson|What is it?
Grandfather|Open it up.
Grandson|{Opens the package. Disappointed.} A book?
Grandfather|That's right. When I was your age, television was called books. And this is a special book. It was the book my father used to read to me when I was sick, {takes book} and I used to read it to your father. And today I'm gonna read it to you.

HERE IS REPLACE_CHARS

def replace_chars(s,li):
for c in li:
s= s.replace(c," ")
return s
if __name__=="__main__":
import test
print('testing function')
test.testEqual(replace_chars(" SampIEam*", ["p", "E", "*"])," Sam I am ")
test.testEqual(replace_chars(" Test1", ["e", "1"])," T st ")
test.testEqual(replace_chars(" Salt@12", ["S", "@"])," alt 12")

Explanation / Answer

Hi,

the code below should work for the same.

f = open('princess.txt"', 'r')
s = f.read() #read file
exclude = set(string.punctuation)
l = " ".join(ch for ch in s if ch in exclude) #join all punctuations with space
punct = list(set(l.split(" "))) #split all punctuations into a list
punct.remove("'") #remove apostrophe

filename = raw_input("Enter filename ") #ask user for filename

f = open(filename, 'r') #open the file
text = f.read()
  
lines = [text.lower() for line in filename] #convert file text to lower case
lines = ''.join(lines.split()) #remove all whitespaces
newline= replace_chars(lines,punct) #call the function given
for line in newline:
line.strip() #print each line with line numbers
print(line)
open_file.close()
