Python TypeError：整数是必需的（got类型列表）

Question

Im trying to take numbers from num.txt(1 3 2) and set it into a array

from array import *
import sys    
f = open('num.txt', 'r')  
l = f.readlines() 
f.close() 
list = [1, 2, 3, 4, 5 ,6]
sclist = [l]
myArray = array('i', [])
myArray.fromlist(sclist)
for i in myArray:
    print(i)

It returns

TypeError: an integer is required (got type list)   

If I change it to myArray.fromlist(int(sclist)) I get

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

Answer 1

Issue here is that l = f.readlines() will return a list of strings, which you then put in another list sclist = [l] , so just do myArray.fromlist(l) .
Make sure to convert the content you read from the file to int prior to doing the myArray.fromlist(l) call.

Answer 2

Assuming your file contains one number per line, you could change the assignment to sclist to:

sclist = [int(s) for s in l]

Hopefully that will work. I also suggest that you avoid using "list" as a variable name (unused in this example), since that will mask the standard Python definition and could cause confusion.
