1. Python Required Parameters If we define a function in python with parameters, so whilecalling that function– it is must send those parameters because they are Required parameters. Example of required parameters in Python # Required parameterdefshow(id,name):print("Your id is :",id,"and ...
2. 关键字参数(Passing arguments by parameter name) 3. 可变的参数个数(Varlable numbers of arguments)

We use an asterisk (*) before the parameter name to denote this kind of argument. For example, # program to find sum of multiple numbersdeffind_sum(*numbers):result =0fornuminnumbers: result = result + numprint("Sum = ", result)# function call with 3 argumentsfind_sum(1,2,3)# fu...
4. Python Function Parameters A function can have default parameters. def multiply(a, b=10): return a*b multiply(12) # 120 multiply(2, 3) # 6 multiply(b=9) # error: None*9 is not valid In this function, if user does not give the second parameter b, it assumes it to be 10,...
In this line we call thecubefunction. The result of the computation of thecubefunction is returned and assigned to thexvariable. It holds the result value now. show_message("Computation finished.") We call theshow_messagefunction with a message as a parameter. The message is printed to the...
endis an optional parameter inprint() functionand its default value is'\n'which meansprint() ends with a newline. We can specify any character/string as an ending character of theprint() function. Example # python print() function with end parameter example# ends with a spaceprint("Hello...
default_arg_values = tuple(p.default for p in parameters if p.default != Parameter.empty) #!argdefs "starts from the right"/"is right-aligned" modified_func = types.FunctionType(modified_code, {'dict_func': func, 'locals': locals}, name=func_name, argdefs=default_arg_values) ...
Below is an example of how we can pass multiple parameter to a single function. Open Compiler defadd(a,b=0,c=0):returna+b+cprint(add(2))# Output: 2print(add(3,2))# Output: 5print(add(1,4,3))# Output: 8 In this example, theadd()function can be called with one, two, or...
