TypeError when split converting string to integer

Question

I get to read a line from a file that contain certain set of numbers per line. My problem is that the input is from a string line and then I need to process it as integer, making the conversion as usually suggested. Although I check previous post on this problem, maybe because I am using structure and split can be the reason why the conversion is not working properly.

Here this error is popping up:

TypeError: not all arguments converted during string formatting
SyntaxError: invalid syntax

This is a snapshot from the code I have done so far:

class Data:
    value1 = 0
    max = 10

class Process:
    value = None    
    def __init__(self):         
        self.input = Data()
    def __del__(self):          
        self.input

    def getValue(self,line):
        counter=0       
        for word in line.split():
            if counter == 0:
                self.input.value1=(int)word

        for number in self.input.max:
            if (number % self.input.value1 ==0):
                print(number)

    def readingFile(self):
        file = open(filename, "r")
        for line in file: 
            self.getValue(line)

Any suggestion what might be missing? I am running on Linux Python 3 using command line to compile.

The type conversion syntax is wrong. It should be `self.input.value1=int(word)` — nu11p01n73R, Jun 18 '15 at 07:05

The invalid syntax comes from -

self.input.value1=(int)word

In python, the casting is not the same as in C/C++/Java , instead of using (datetype)variable you have to use datatype(variable) , though that is only for primitive datatypes. For other datatypes, you do not need casting, as python is a dynamically typed language.

You should use -

self.input.value1 = int(word)

EDIT:

For the new error the OP is getting -

{{ for number in self.input.max: }} >> TypeError: 'int' object is not iterable.

You cannot iterate over an int object, just as the error indicates, to me it looks like both self.input.value1 and self.input.max are single integers, so you may want to do -

if self.input.max % self.input.value1 == 0:
    print(self.input.max)

Now it gives the new error: {{ for number in self.input.max: }} >> TypeError: 'int' object is not iterable. Thanks a ton! – Daniela Martínez Jun 18 '15 at 07:11
The line that contains: {{ for number in self.input.max: }} – Daniela Martínez Jun 18 '15 at 07:14
yes, like the line suggests you cannot iterate over integer, what do you want to accomplish with that? – Anand S Kumar Jun 18 '15 at 07:15

Updated the answer for that as well , please check if that is really the requirement – Anand S Kumar Jun 18 '15 at 07:19

Thanks a lot. your suggestions solved the problem! I just needed to use "range" for the "for" loop to work with int – Daniela Martínez Jun 18 '15 at 07:31
