I need to find integers of a file. I need to get the average of these ints (I already have this part figured out). I get the error: "error on input []: Can't convert 'int' object to str implicitly"

EDIT - Code is working. Thank you everyone! DiCaprio helped me to come up with final solution.

I edited my final code to be this:

```   def average_ints():
integers = []
num_ints = 0
avg = 0
with open("file") as f:
for line in f:
for i in line.split(' '):
integers.append(int(i))
num_ints = num_ints + 1
avg = (sum(integers))/((num_ints))
return avg
```

How can I find the integers of this file?

use cast `int(x)` to transform str to int. By default everything is read from file as str.

```def average_ints():
integers = 0
num_ints = 0
avg = 0
with open("associate.txt") as f:
for line in f:
for i in line:
# if i in line: <- this should always be True
integers += int(i)  # + integers <- += adds and stores
num_ints = num_ints + 1
avg = integers/num_ints
return avg
```

EDIT:

I just thought you probably get a problem with the `for i in line:` part. Line would need to be split. try using `for i in line.split(' ')` assuming your ints are split by a space.

EDIT 2:

If it is one int per line use:

```def average_ints():
integers = 0
num_ints = 0
avg = 0
with open("associate.txt") as f:
for line in f:
integers += int(line)
num_ints = num_ints + 1
avg = integers/num_ints
return avg
```

Find sum of integers in a file which contains any characters , You are given a text file which contains any type of characters. You have to find the sum of integer values. Examples: Input : text.txt Let contents of test.txt be : :-,  C++ Program For Find The Sum of Integers In a File. Problem:- C++ adding numbers from an input file or C++ Adding Numbers From an Input File using File Handling or c++ read text file line by line. or c++ adding numbers from a file or c++ count numbers in a file or how to read numbers from a file in c++ or c++ average numbers from file or count number of integers in a file c++ or determining largest smallest & mean from file input or write a program that opens the file reads all the numbers

The problem here is that 'int' in lines is a string, and you need to convert it to an integer first. You can do this by replacing 'int' with int(int).

This is assuming that there are only numbers (characters that can be represented as floats or integers) in the file. If not, you need to account for that.

It's also not a good idea to name a variable after a built-in function, so I would change the name int to something else.

Extract numbers from a text file and add them using Python , Through this program, we can extract numbers from the content in the text file JSON, and CSV to a File in Python · Python | Finding 'n' Character Words in a  "file_name" is not a good name for a file object. "words" is not a good name for a collection of numbers represented as strings. "shift_l5 = words[4]" and "shift_l6 = words[5]" will fail, because you have only 4 numbers. Note that print "3" and print 3 produce the same results.

You probably shouldn't use "int" as variable as it's a built in and if you try to reference it later you wont be able to.

So by the looks of it you want to take all integers in a file and average them? Here's a function that will do it:

```def avg_ints(x): # Where x is a file
total = 0
count = 0
lines = x.readlines()
for line in lines:
for character in line:
try:
character = int(character)
count += 1
total += character
except ValueError:
pass
return total/count
f = open("associate.txt")
print(avg_ints(f))
```

Reading from files, where numbers.txt is the name of the text file we want to read from. System.exit(​0); } // Find the smallest and largest numbers in the file int smallest = input.

Have you tried using regular expressions? It might work a little easier for you.

Read the file and using an expression like this should parse the file for integers.

I hope this helps.

Reading data from file, The next task is to compute the average of the numbers in the file. A newcomer to programming might find it confusing to see that one problem is solved by  minimum and maximum in a file . minimum and maximum in a file. idks16. Hi I have to find the minimum and maximum number from the input file and output it on another

Or why not this, a straightforward solution:

```def average_ints():
with open("associate.txt") as f:
integers=int(f.read())
num_ints=len(str(integers))
avg = integers/num_ints
return avg
```

Just directly convert to integers without going trough each character

And if there are non-numeric values:

```def average_ints():
num_ints=0
integers=0
with open("associate.txt") as f:
for i in f.read():
if i.isdigit():
num_ints+=1
integers+=int(i)
avg = integers/num_ints
return avg
```

How to parse a text file in Python and get the sum of the numbers , Assuming file has only numbers, use open() in built function to extract content Unlike searching on DuckDuckGo, when you search on Google, they keep y. The BufferedReader class doesn’t provide any direct method to read an integer from the user you need to rely on the readLine() method to read integers too. i.e. Initially you need to read the integers in string format. The parseInt() method of the Integer class accepts a String value, parses it as a signed decimal integer and returns it.

How to read integers from a file in C, Well you can do one thing, read the characters from the file, and convert them with [code ]atoi(char Where can I find a C program to write “N” numbers to a file​?

##### Comments
• `int` is a built-in, never use that name for your objects
• you probably should provide a sample of your file and full error message
• Are the integers in the file associate.txt all on one line or is it one integer per line?
• I'm confused by "if int in line:" do you mean to check if the line in the file is an integer? If so please look at the .is_integer() extension method; docs.python.org/2/library/stdtypes.html#float.is_integer
• @BobbyDurrett It is one integer per line.
• To extend on this I think you should be checking that the input is an int before attempting to cast it.
• @MadisonCourto: or use EAFP and catch `ValueError` exception
• @AzatIbrakov agreed.
• I understand that I need the line.split(' ') part, but I don't understand why. What purpose does it have in the function? @DiCaprio
• This is giving me the incorrect return value. Returned:3.8571429. Exepcted: 9.0
• @ncohen10 Sorry, then i have no clue
• The comments say it is one integer per line so this is probably overkill.
