The same functionality can be provided using python for and the range()
function, like:
for i in range(0, 10):
print i
Though because of the way python works you don't need to use this type
of loop anywhere near as often as in other languages. For example in
java (and c++, but my c++ is so rusty I'm not going embarrass myself
trying to write an example) you're constantly doing things like looping
over an array:
public void main(String[] args) {
int[] foo;
/* then later after foo has been initialized to whatever: */
for (int i=0; i<foo.length; i++) {
System.out.println(foo[i]);
}
}
The equivalent code in python is much cleaner, after foo has been
initialized to whatever:
for each in foo:
print each
Hope this helps,
