Which code entry is more correct in terms of Python?

Question

Python

There is a code:

a = 1
while <условие>:
    print (a)
    a += 1

Which notation is more correct and why "while a != 10: " or "while a < 10:"

Answer 1

for a in range(1, 10):
    print a

while is generally better not to use for this type of loops

Answer 2

a < 10 is closer to "self-documenting" code, and therefore preferable.

Answer 3

Which notation is more correct and why "while a != 10: " or "while a < 10:"

These records are semantically unequal. Specifically, in your example, they will work the same way, but if at some point you need to add 2 to a , and not 1, then the record while a != 10will turn into an endless loop. And Dmitry Alexandrovich
has already answered how correctly from the point of view of a pythonist .
