If you try to open a non-existent file in "r+" mode in C you should get an
error, too. The following C code
FILE * f;
int i;
char filename[100];
for (i=0; i<10; i++) {
sprintf(filename, "foo%d.dat", i);
FILE * f = fopen(filename, "w");
/* write stuff to file */
...
fclose(f);
}
translates into this piece of Python:
for i in range(10):
filename = "foo%d.dat" % i
with open(filename, "w") as f:
# write stuff to file
