Python Question

I tried this code from this question - Python insertion sort. I modified the code a bit, got rid of the

`eval()`

`def sort_numbers(s):`

for i in range(1, len(s)):

val = s[i]

j = i - 1

while (j >= 0) and (s[j] > val):

s[j+1] = s[j]

j = j - 1

s[j+1] = val

print s

x = raw_input("Enter numbers to be sorted: ").split()

sort_numbers(x)

It doesn't work for a few too many test cases.

`In: 1001 101 20 24 2000`

Out: 1001 101 20 2000 24

I've also tried with some negative numbers. The code doesn't work. Why is this so?

Answer

This is because `x`

is a List of strings and not integers. You can correct your input example by placing this code before `sort_numbers`

:

```
x = [ int(v) for v in x ]
```

**Original result**:

```
Enter numbers to be sorted: 1001 101 20 24 2000
['1001', '101', '20', '2000', '24']
```

**Result after adding that line**:

```
Enter numbers to be sorted: 1001 101 20 24 2000
[20, 24, 101, 1001, 2000]
```

Notice that now the List shown from `print s`

does not have elements surrounded by quotes
