Q1) What is Python?
Python is a mediated language, effective program. It includes sections, exemptions, active signals, high-quality data types, and classes. Python connects power with a very clear word. It has many interfaces and libraries, as well as several windows systems, and can be used for C or C ++. It can also be used for additional languages for applications that need to be learned in the program. Finally, Python is portable: it operates in many different types of Unix, in March, and MS-DOS, Windows, Windows NT and OS / 2 computers.
Q2) Is there a tool to help you find a mistake or make a diagnostic situation?
Pychecker is a secure and intelligent device that tries to point the Python code and warns of distortions and patterns.
Pylint is another tool that ensures that the system satisfies the voting standards, and also allows you to write keys to include specific attributes.
Q3) What are the rules for local and global variables in Python?
In Python, the variables are referred to only as global operational. When replacing a new value for the body, it is now considered to be a local. When replacing the value of new jobs, the changes are inadequate, and you should clearly state ‘international’.
On the one hand, an internationally-funded effort to provide a barrier to the unwanted effects. On the other hand, if the world is universal reference world, you had all the time in the world. It may be necessary to tell how each international reference of any reference to the work or part of the module has been exported. This problem is contrary to the use of evidence affecting international influence.
Q4) How can I share the change through the Global module?
The cost-sharing method for sharing information through a single-program category is to create a custom module (usually called CF or CFG). You just need to put the module in all the application forms; Module becomes international. Because there is one example in each section, the changes made to the product are shown at each location.
config.py: x = 0 # The average value of "x" for the value of the item mod.py: export patterns config.x = 1 main.py: export patterns import mode config.X printing
Q5) How do I copy the Python object?
Generally, try copy () or copy.epcopy () for listeners.All items can not be copied, but most are able to.
Some devices can be easily copied. There is no copy of the procedure:
enddict.copy = ()
The coil can be printed with:
new_l = l [:]
Q6) How can I get the product or product attribute?
For example, a specimen class, dir (x) returns a list of names that include the attributes and examples of the methods and features described in the class.
Q7) Is There An Equivalent Of C’s “?:” Ternary Operator?
Q8) How to convert a Number to String?
To change, for example, 144 ‘144’, using Str-built. If you want a twelve or eight representation, using hex () or combination (OCT) integrated functions. Using a comfortable mode, use %% operators, for example, ‘% 04D’ 144% activity ‘0144’ and ‘% .3f’% (1 / 3.0) to generate ‘0.333’.
Q9) What is a Negative Expression?
The Python series is shown in positive and negative numbers. For the exact numbers 0 is the first series 1 is the second example, and so on. On the other hand, -1 and -2 indexes continue to return (after the final stage) and so on. Think about the SEQ [n] same as the SEC [Boston (SEC) -n].
Use the base scale can be very convenient. For example, S [: – 1] is all letters, except for the last child, the benefits to eliminating the end of the letter final.
Q10) How Do I Apply A Method To A Sequence Of Objects?
Use a list by understanding it:
Result = [obj.method () for obj list]
