# Why is VS Code unable to convert this List into a Int?

## Question:

```
def load_matrix():
matrix = sys.stdin.read()
matrix = matrix.strip().split('n')
matrix = [row.split(' ') for row in matrix]
for m in matrix:
matrix=[int(l) for l in m]
print("n Data Loaded Sucessfully")
print("n")
var=pd.DataFrame(matrix)
return var
```

Look at this piece of code. I am trying to take a matrix directly as the input for the program, but the read function takes the input as a list of strings. To convert it into a int object for performing math functions, i have used the code above. running fine with online compilers but VS Code keeps throwing an error saying:

ValueError: invalid literal for int() with base 10: ‘4x1a’

(when given the input as:-

This )

From what I have researched, this happens when the value passed cannot be converted into an integer.

When I run a similar code in Jupyter notebook it runs smoothly.

Your Help will be appreciated.

## Answers:

As pointed in the comments, `x1a`

is the unicode character to indicate `EOF`

. I really don’t know what you are trying to achieve in your code, but I can help you fix it.

In my knowledge, `x1a`

takes 1 length in the `str`

, so removing it would be easy as it always be at the end of the `matrix`

.

```
matrix = matrix.strip().split('n')
matrix = [x if 'x1a' not in x else x[:len(x)-1] for x in matrix]
```

It checks for `x1a`

, if it is found, it removes it from the `matrix`

.

Output (It also includes the edited `matrix`

, or to be exact newly created `matrix`

):

```
['1 2', '3 4']
Data Loaded Sucessfully
0
0 3
1 4
```
