To check if a string has alphabets or numbers in Python, we can use some built-in methods like isalpha() and isdigit(). isalpha() returns True if all characters in a string are alphabets (letters), and False otherwise. isdigit() returns True if all characters in a string are digits (numbers), and False otherwise. Here are two examples that demonstrate how to check if a string has alphabets or numbers: To Check if a String has Alphabets or Numbers Example In this example, we first prompt the user to enter a string using the input() function. We then check if the string ... Read More

The possible solution could be to update policy tag like thisUpdate the policy tag like this:And try the serviceAnother possible option is to change /ws_policy/ to /standard/ and you will be able to use PHP Soap Client to consume Web Service.Go to Web Service Administration in your SAP ECC system using SOAMANAGER -> SOA-ManagementIn URL of the browser, you can see the “ws_policy” tag -> replace this with “standard” and you will have WSDL without policy tag.

In Python, you cannot pass arguments by reference like you can in other programming languages like C++. However, there is a way to simulate pass by reference behavior in Python using mutable data types like lists and dictionaries. In Python, arguments are passed by assignment, which means that the parameter name in the function definition becomes a reference to the object passed as an argument. Therefore, there is no direct way to pass arguments by reference in Python. However, you can achieve a similar effect by passing a mutable object like a list or a dictionary to a function ...

For the given code above the solution is as followsExampleclass CustomValueError(ValueError): def __init__(self, arg): self.arg = arg try: a = int(input("Enter a number:")) if not 1 < a < 10: raise CustomValueError("Value must be within 1 and 10.") except CustomValueError as e: print("CustomValueError Exception!", e.arg)OutputEnter a number:45 CustomValueError Exception! Value must be within 1 and 10. Process finished with exit code 0

A suffix is defined as a letter or group of letters added at the end of a word to make a new word. Let's say you have a list of suffixes, which are groups of letters that can be added to the end of a word to change its meaning. You want to check if a given string ends with one of these suffixes in Python. To check if a string ends with a suffix in a list Example In this example, we first define a list of suffixes that we want to check if the string ends with. ... Read More

To check if a string or a substring of a string ends with a suffix in Python, there are several ways to accomplish this. Here are some examples: Using the endswith() Method The endswith() method checks if the string ends with a specified suffix and returns a boolean value. To check if a substring of a string ends with a suffix, you can use string slicing to get the substring and then apply endswith() on it. Example string = "hello world" suffix = "world" if string.endswith(suffix): print("String ends with suffix") Output String ends with ... Read More

The code can be written as follows to catch the exceptiona, b=5, 0 try:    if b != 0:        print a/b    else:        a/b        raise ZeroDivisionError except Exception as e:        print eWe get the following outputC:/Users/TutorialsPoint1/~.py integer division or modulo by zero

All python exceptions are not runtime errors, some are syntax errors as well.If you run the given code, you get the following output.File "C:/Users/TutorialsPoint1/~.py", line 4 else: ^ SyntaxError: invalid syntaxWe see that it is syntax error and not a runtime error.Errors or inaccuracies in a program are often called as bugs. The process of finding and removing errors is called debugging. Errors can be categorized into three major groups:Syntax errors 2. Runtime errors and 3. Logical errorsSyntax errorsPython will find these kinds of errors when it tries to parse your program, and exit with an error message without running ... Read More

We can write custom exception classes with error codes and error messages as follows:class ErrorCode(Exception):     def __init__(self, code):         self.code = code     try:     raise ErrorCode(401) except ErrorCode as e:     print "Received error with code:", e.codeWe get outputC:/Users/TutorialsPoint1/~.py Received error with code: 401We can also write custom exceptions with arguments, error codes and error messages as follows:class ErrorArgs(Exception):     def __init__(self, *args):         self.args = [a for a in args] try:     raise ErrorArgs(403, "foo", "bar") except ErrorArgs as e:     print "%d: %s ...

We can use the finally clause to clean up whether an exception is thrown or not:try:   #some code here except:   handle_exception() finally:   do_cleanup()If the cleanup is to be done in the event of an exception, we can code like this:should_cleanup = True try:   #some code here   should_cleanup = False except:   handle_exception() finally:   if should_cleanup():     do_cleanup()
