circuit mechanism in Python:
def a(): print 'this is A!' return 1def b(): print 'this is B!' return 1def c(): print 'this is C!' return 1if a() or b() and not c(): print 'OK!'
If the priority of and is higher than or, shouldn't B be followed by C and then A? How can I output A directly?
In fact, this is also the case in other languages, but I didn't care about it at the time. This is
Core IdeasThe expression is left-to-right, and if the left logical value of OR is True, then all expressions (whether and or or) that are short-circuited or are directly output or left-hand expressions. The expression is left-to-right, and if the left logical value of and is False, then all the and expressions are shorted, until an or appears, and the output and left expression to the left of or is involved in the next logical operation. If the left of the or is False, or if the left side of and
In peacetime development process often encounter needs to simulate post or get request, of course get generally directly through the browser can also be convenient and quick. Zhengxiao See the Internet also has a lot of software version of the HTTP simulator, the function is also very powerful. Zhengxiao recently in learning python, just hand idle panic, with Python
The previous round spoke of Python's history and its basic applications. For this round, you can say Python operators. Very simple. Operators, as the name implies, are taught in math classes in school, subtraction. +-*/This is the way the computer is expressed. The only difference is that in a programming language, the expression is more special than that. There is a division that has a% of the remainder. For example, let's first say, divisible. To di

The next step is to wait patiently for a few minutes (5-10 minutes of poor PC performance), and the following interface is successfully run3. See above this interface instructions to start a successful, and then the normal operation of the phone as a point, then use the ADB tool to check the device, open the CMD input>ADB devicesThe
