Python 3.6从文本文件中删除了不以元音开头的单词

Question

I am learning Python 3.6. I would like to know how to remove a word that does not start with a vowel reading in from a text file. I have already a text file called someStates.txt so I don't have to read in from a path for now.

When I run the code I get someState.txt not defined . I want the output to create a text file with words that don't start with a vowel.

What am I doing wrong?

infile = open('someStates.txt', 'r')
infile.close()

vowels = ('a', 'e', 'i', 'o', 'u','y','A','E','I','O','u','Y') 

filteredStates.txt = [state
                    for state in someStates.txt
                      if state[0].rstrip().lower()
                        not in vowels] 
infile = open('filteredStates.txt','w')
infile.close()
print( 'infile')

Answer 1

''' Im new to this, listening to many of the advice here this is what I got

'''

#input

infile = open('someStates.txt', 'r') # read in a text file frome my directory

#process

filterState=[line.rstrip() for line in infile] 
infile.close() 

vowels = ('a', 'e', 'i', 'o', 'u','y','A','E','I','O','U','Y')

filterState=[state for state in filterState
                      if state[0].rstrip().lower()
                      not in vowels]
infile.close()


#output


print(filterState)

Answer 2

infile = open('someStates.txt', 'r')
infile.close()


                    for state in someStates.txt

That is not how it works ;)

open() returns a file object: https://docs.python.org/3/library/functions.html#open

From the file object, you can then read data into a string variable with data = infile.read() . (Do this before closing the file.)

Then you need to split the string into words with words = data.split() . Only after that you can loop over the words.
