") print ("a = ", a)test() b = Falseexec ("b = True")print ("b = ", b) In python 2.x and 3.x, you will find that their results are different: 2.x：a = Trueb = True 3.x：a = Falseb = True Why? Because exec in 3.x is changed from a statement to a function, the variables in the function are local by default, that is The tw

Python variables and data types, python VariablesIn hexadecimal notation, the prefix 0x and 0-9 a-f are used to indicate that the string is any text enclosed by ''or" ". a boolean value is True and False. or not is a special value in Python, use None. None cannot be understood as 0, because 0 is meaningful, none is a s

times in the previous chapters. However, the assignment operation in the Python language is much more interesting. For example, you can assign multiple values to multiple variables at the same time.>>> x,y,z = 1,2,3>>> print(x,y,z)1 2 3?? In the above code, the three-in-one

Suppose we have such a py file:def fun (): print ' Dada ' return u ' welcome 'Class Base: A = Fun () def __init__ (self,c): self.b = U ' Hello ' Print SELF.ABase1 = Base ()(1) First, it is easy to see that a is a class variable, B is an instance variable, and C is a local variable.(2) Explain how the memory is allocated when we execute the PY file. The Func method is first

Local and global variables of PYTHON functions, python global variables With such a piece of PYTHON code, anyone who is engaged in C Language Development knows that if global variables are defined and function

the function (assuming there is no variable of the same name in the function). However, I do not encourage you to do so, and you should try to avoid doing so, because it makes the reader of the program not sure where the variable is defined. Using the global statement makes it clear that the variable is defined in the outer block. Example 7.4 using the global statement #!/usr/bin/python# Filename:func_global.py def func ():Global X

However, after the program is executed for a certain period of time It seems that your fifth thread is suspended, which makes it impossible to release the lock resource.A newbie to Python Multithreading Use the join function of the threading module to check whether the thread is finished.If you can only use the thread module, you can use the flag, but the efficiency is relat

In python, the variable scope rules are somewhat different. In programming languages such as C/C ++ and java, global variables defined outside the function can be directly accessed within the function by default, however, this problem may occur in python. The following is an example. Test. py :#! /Usr/bin/pythonCOUNT = 1def func (): COUNT = COUNT ++ 1 func ()

variable x is a new variable print (x + 5) # The name is the same, however, the new variable x is used. Continue assignment x = 'hello python'print(id(x))print(x) At this time, x becomes a new variable, and the variable type also changes due to the change of the assigned data type. Here, id () is a Python built-in function. See https://docs.python.org/3/library/

When you declare variables within a function definition, they are not related to other variables with the same name outside the function, that is, the variable name is local to the function. This is called the scope of the variable. All variables are scoped to their defined blocks, starting with the point where their names are defined.Using local variablesExampl
