This article mainly introduces the loop-related functions range, enumerate, and zip in the python advanced tutorial. These functions are often used with loop programs to complete loops, for more information, see the "loop" section. We have discussed the basic loop Syntax of Python. In this section, we will be exposed to more flexible loop methods. Range () In Py

fail. Therefore, to ensure security, the return value of send must be checked, and if the transaction fails, the etheric currency is rolled back. It would be better if you use transfer.Contract related This (the type of the current contract):Represents the current contract, which can be explicitly converted to address Selfdestruct (Address recipient):Destroys the current contract and sends all its funds to the given address. Suicide (address recipient):Aliases for Selfdestruct

y in the function definition (line 2nd) We call the formal parameters.Thinking and practicing How do you define functions and variables under python? What is the main difference between a function and a variable defined in the C language? What do you need to be aware of when modifying global variable values? How do I check the help documentation for the SQRT function? Assignment statement x, y, z = 1, 2, 3 What is the result?

point is within the polygon Contains contains, just the opposite of within. Poly1. Contains (PtB) is to change the subject and the parameters. overlaps overlap, as if only between two polygons can overlap Poly2. Overlaps (poly3) Returns 0 means no overlap, 1 for overlap Let's take a look at the simple geographic data processing geoprocessing of the Polygon: Hand: Poly3. Intersection (POLY2) And: Poly3. Union (Poly2) Poor: Poly3. Difference (poly2) Supplement: Poly3. Symmetricdifference (Poly2)

PHPisset () function and empty () function are different. Empty checks whether a variable is null, and isset determines whether a variable has been set. Just as the name implies, I took some detours at the beginning: When a variable value is equal to 0, empty checks whether a variable is "empty ", isset checks whether a variable has been set. This so-called "name implies" leads me to a detour: When a variable value is equal to 0, empty () will also be True) Empty checks whether a variable is "nu

Notes for call_user_func functions. Notes for the call_user_func function: parseerror: syntaxerror, unexpectedt_list, and expectingt_stringin are always prompted when using this function today. Refer to the official notes for the call_user_func function. Parse error: syntax error, unexpected t_list, expecting t_string in When using this function today, the above problem is always prompted. The precautions for using the tool are not described in the o

Python advanced tutorial-loop functions: range, enumerate, zip, and pythonenumerate In the "loop" section, we have discussed the basic loop Syntax of Python. In this section, we will be exposed to more flexible loop methods. Range () In Python, if the in after a for loop follows a sequence, the sequence elements used for each loop are not the subscript of the sequence. We have used range () to control the f

learn more about objects in the later class chapter. If you've already used help () in Python, you've seen the use of docstings! All it does is grab the __doc__ property of the function and show it neatly to you. You can try this on the function above-just include help (Printmax) in your program. Remember to press Q to exit help. Automation tools can also extract documents from your program in the same way. Therefore, I strongly recommend that you write a document string for any formal function
