for loop in python
There are two types of loops in Python, for and while.
The "for" loop
For loops iterate over a given sequence. Here is an example:
primes = [2, 3, 5, 7]
for prime in primes:
print(prime)
For loops can iterate over a sequence of numbers using the "range" and "xrange" functions. The difference between range and xrange is that the range function returns a new list with numbers of that specified range, whereas xrange returns an iterator, which is more efficient. (Python 3 uses the range function, which acts like xrange). Note that the range function is zero based.
# Prints out 3,4,5
for x in range(3, 6):
print(x)
It’s great to come across a blog every once in a while that isn’t the same out of date rehashed material. Fantastic read. Best types of nat service provider.
