Python列表未转换为整数

Question

Hi I'm trying to convert my file back into a integer, the file reads numbers but is stored in a string and I'm trying to convert it into a integer the error I keep getting is:

TypeError: int() argument must be a string, a bytes-like object or a number, not 'list'

My code:

with open('Position_of_Words.txt') as d:    #my file 
    for line in d:
        print (int(line)) #Trying to convert into a integer


position_of_words_list = line.split(" ")  #make into list
print (position_of_words_list)  

Answer 1

You are trying to convert whole string to integer.

First split that string, then cast integer on each item.

with open('Position_of_Words.txt') as d:    #my file 
    for line in d:
        if line: #checks if line is not empty    
            position_of_words_list = list(map(int, line.split())) 
            print (position_of_words_list)

#since there is only one line in txt file, you can also use something like below
with open("input.txt","r") as f:
    position_of_words_list  = list(map(int, f.read().split()))
    print position_of_words_list 

Since you have only one line, above should work. If there are more than one line, you can append each line into the list.

position_of_words_list = [] #which will be list of lists
with open('Position_of_Words.txt') as d:    #my file 
    for line in d:
        if line: #checks if line is not empty    
            position_of_words_list.append(list(map(int, line.split())))
    print (position_of_words_list)

Since the file has only one line and the line read as string you are getting that error.

with open('t.txt','r') as d:
    for line in d:
        position_of_words_list = [int(i) for i in line.split(' ')]
    print position_of_words_list

Answer 3

Maybe is error in formatting the code, but the line variable is not inside the for block.

Also, if you have spaces in the lines you cannot convert it into int. It will only work if the line is a string with numbers only (no letter or any other special char like spaces).

Concerning the error itself, it looks like the iterator is converting the line into a list (probably of bytes?). Try to use str(line).
