8.4 Open the file romeo.txt and read it line by line. For each line, split the line into a list of words using the split() function. The program should build a list of words. For each word on each line check to see if the word is already in the list and if not append it to the list. When the program completes, sort and print the resulting words …

gistfile1.txt

fname = raw_input("Enter file name: ")
fh = open(fname)
lst = list()                       # list for the desired output
for line in fh:                    # to read every line of file romeo.txt
    word= line.rstrip().split()    # to eliminate the unwanted blanks and turn the line into a list of words
    for element in word:           # check every element in word    
        if element in lst:         # if element is repeated
            continue               # do nothing
        else :                     # else if element is not in the list
            lst.append(element)    # append     
lst.sort()                         # sort the list (de-indent indicates that you sort when the loop ends)
print lst                          # print the list

fname = input("Enter file name: ")
fh = open(fname)
lst = list()
for line in fh:
word_split = line.split()
for word in word_split:
if word not in lst:
lst.append(word)
else:
continue

print(sorted(lst))

This one is some tricky with two nested loops. If someone has a simpler code is welcome! :)

This is the simpler method and workable too:

fname = input("Enter file name: ")
fh = open(fname)
lost=list()
for line in fh:
word =line.split()
for n in word:
if not n in lost:
lost.append(n)
lost.sort()
print(lost)

Hello my friend, I found a different solution :)

Check it...hehehe

fname = input("Enter file name: ")
fh = open(fname)
lst = list()
a = []
for line in fh:

line = line.rstrip()   
wds = line.split()
a = a + wds
a.sort()

del a[6:8]
del a[12:14]
del a[19:20]
del a[20:22]

print(a)

Thank you!
btw now in python3 is input not raw_input

fname = input("Enter file name: ")

try:
fh = open(fname)
except:
print("invalid file name")
quit()
lst=list()
for line in fh:
line=line.rstrip()
line=line.split()
for words in line:
if words in lst:
continue
else:
lst.append(words)
lst.sort()
print(lst)

hi guys, this is my code and it works but was just wondering why do some code on top not need line=line.rstrip()?
is it because print() does not print the \n out?

fname = input("Enter file name: ")
fh = open(fname,'r')
lst = []
for line in fh:
    text1 = line.split()
    for word in text1:
        if word in lst: continue
        else:
            lst.append(word.strip())
lst.sort()
print(lst)

what is the lst = [ ] if I may ask. I dont understand that line much

name = "mbox-short.txt"
handle = open(name)
counts = {}
words = []

for line in handle:
line = line.rstrip()
if not line.startswith('From '):
continue
word = line.split()
words.append(word[1])

for word in words:
if word in counts:
counts[word] += 1
else:
counts[word] = 1
print(sorted(counts,key=counts.get, reverse = True)[0]+' '+str(sorted(counts.values(), reverse=True)[0]))

Thank you!

Hi, this is a code i used to display in the format asked by the exercise

with open('admin panel.txt','a') as s:
pplzz tell correct line

fname = input("Enter file name: ")
fh = open(fname)
lst = list()
for line in fh:
line = line.split()
for ch in line:
if ch not in lst:
lst.append(ch)
lst.sort()
print(lst)

I have a question, I am really new to codding
instead of opening file I just have used the text as variable, everything is working but it is not sorting itself, please help

fname = '''But soft what light through yonder window breaks

fname = '''But soft what light through yonder window breaks It is the east and Juliet is the sun Arise fair sun and kill the envious moon Who is already sick and pale with grief''' fname = fname.split() lst = list(fname) fname = fname.sort() print(lst)

This will sort it. But remember that upper case will sort before lowercase.

fname = '''But soft what light through yonder window breaks

Arise fair sun and kill the envious moon

### i also had problem with 'double' and is there anybody can help further?thx
actally i have understood that we use a blank space after'from'
or we write a conditional sentence like if not len(line) <=3 then continue
the goal is to ensure that we avoid those blank lines
but i still have the question that why cannot use rstrip() here to help avoid those blank lines
for i had tried it but if we do not use a blank space after'from' or write a conditional sentence
the result still doubles
why is that on earth?

fname = input("Enter file name: ")

fh = open(fname)
wod=[]

wod.sort()

print(wod)

:)

file = input("Enter a file name:")
handle = open(file)
read = handle.read()

lst = list( )
for line in read:

for line in fhandle:

[words.append(i) for i in line if i not in words] // without the need of 'for' loop

    if i not in words:
        words.append(i)

words.sort()

   lst.append(words[1:2])

for element in lst:
for x in element:

print("There were", count, "lines in the file with From as the first word")

Not the best but works well. :)

        continue

#print(q)

#print(lst2)
lst.sort()
print(lst)
#print()

I don't know why when I run the code I get none, help me.
