[Python] For loop overriding outer variables instead of creating new ones

I stumbled upon another basic concept I've missed in Python:

Having this basic for (foreach) loop:

x = 15
for x in range(10):
continue
print(x)


The value for x I expected was 15, but instead I got 9.

The same code snippet in C returns x's original value – 15:

#include <stdio.h>

int main(void)
{
int x = 15;
for (int x = 0; x < 10; x++)
{
continue;
}
printf("%d", x);
return 0;
}


I can't figure out how the variable scope works here.

Since x is declared outside the for loop scope, shouldn't a new local variable be created during the lifetime of the loop?

Why is x being overridden in the Python version then?
