python debug print

Conceptually, one is the return value, one is the printout.Difference One: Return is the end of the function is usually placed in the end, when you write back after the return of something is not performed the followingdef Renshu (x, y): h=x+y print (h) return H print (' Hello word ') print (Renshu (3,7))The result after execution is that Hel

determine the end of the output (default ' \ n '), by naming the parameter file to determine where to output (the default sys.stdout), by naming the parameter Fiush to determine whether the output uses the cache ( Default false).>>> Print (1,2,3)1 2 3>>> Print (1,2,3, Sep ='+')1+2+3>>> Print (1,2,3, Sep ='+', end ='=?')1+2+3=?2. Sep, end, file, flush must be pas

Python uses a for while loop to print the Yang Hui triangle exercise (list index exercise).Yang Hui Triangle is a number of triangular tables, the general form is as follows:11 11 2 11 3 3 11 4 6) 4 11 5 10 10 5 11 6 15 20 15 6 1.......................The most essential feature of the Yang Hui Triangle is that its two hypotenuse is made up of the number 1, while the remaining number equals the sum of two nu

I. NET A, recently in the data structure and algorithm analysis, the middle involved in some of the more interesting algorithmic problems, intended to use Python to achieve the following. The reason for choosing Python is to familiarize yourself with the syntax of Python and pycharm basic applications.In this article, the algorithm is: all permutations of the pri

In the Python error debugging process sometimes need to print the current Python file error line, below to describe the method: Import Sys Try A = [+] Print A[3] Except S=sys.exc_info () Print "Error '%s ' happened on line%d"% (S[1],s[2].tb_lineno)

Microsoft's cross-platform development tool has recently been interested in Microsoft's Visual Studio code. Light weight and simplicity.Version iterations are also very fast, now nearly 1.3.1 version, the function is also more perfect.Let's briefly describe how I ran debug Python in vs code today.Because I have not seen the relevant article description on the Internet. I will find out for myself, the basic

The print () function in Python and the System.out.print () function in Java all have the function of printing strings.In Python:Print ("hello,world!")The output is: hello,world!In Java:System.out.print ("hello,world!");The output is: hello,world!As we can see, the use of these two functions is the sameThe print () function also has this usage:Print ("1+1=", + +)

Overview Python comes with pdb to debug code. Set breakpoints import pdb ... pdb.set_trace() .... Common commands Set a breakpoint for break or B Set breakpoints Continue or c Continue Program Execution List or l View the code segment of the current row Step or s Go to function Return or r Run the code until the current function returns

1 naming conventions for variable names:Consists of numbers, letters, and underscores, but you cannot name a variable with a number. For example A, B, C, name, User1 user_id, and so on can be used as variable names.1A,2B 3CD and so on are not. Special Note that you cannot use keywords in python syntax as variable names. Common "Class" "and" "as" "Insert" "while" "Elif" "Else" "Del" and so on.Variables in Python
