You can put comments anywhere in an if...elif...else statement, ie before each of these blocks or within each of these blocks. Note that you cannot put multiline comments before elif and else blocks though, as these comments are actually strings which imply a break in the whole construct. For example,# If check if True: # Another Comment style print("If block") # Else if statement elif False: # Another Comment style print("elif block") # Else else: # Another Comment style print("Else block")This will give the output:If block
You can do this directly if you are surrounding your multiline if statements conditions in a parenthesis. For example,if (cond1 == 'val1' and cond2 == 'val2' and # Some comment cond3 == 'val3' and # Some comment cond4 == 'val4'):However, this is not possible if you try to do this without a parenthesis. For example, the following code will give an error:if cond1 == 'val1' and \ cond2 == 'val2' and \ # Some comment cond3 == 'val3' and \ # Some comment cond4 == 'val4':
A home network is a small sized LAN that is used to connected devices within the small area of a home. It facilitates sharing of files, peripheral devices, programs and Internet access among the computers in a home. Home networks may be wired, i.e. connections within devices are done with cables; or wireless, i.e. connections are provided using Wi-Fi and Bluetooth.Purpose of Home NetworksModemRouterNetwork SwitchNetwork BridgeHome Automation Controller
There is no special .. ("dot dot") notation syntax in python. You can, however, see this in case of floats accessing their properties. For example,f = 1..__truediv__ # or 1..__div__ for python 2 print(f(8))This will give the output:0.125What we have is a float literal without the trailing zero, which we then access the __truediv__ method of. It's not an operator in itself; the first dot is part of the float value, and the second is the dot operator to access the object's properties and methods. This can also be achieved using:>>> f = 1. >>> f 1.0 >>> f.__truediv__
From the Python docs:Operators in the same box group left to right (except for comparisons), including tests, which all have the same precedence and chain from left to right — see section Comparisons — and exponentiation, which groups from right to left).So the ** operator(exponentiation) is right to left associative. For example,2 ** 3 ** 4 will be evaluated as: (2 ** (3 ** 4))For example,print(2 ** 3 ** 0)This will give the output:2

If you want to get an inversion of only first 16 bits of a number, you can take a xor of that number with 65535(16 1s in binary). Forgetting a 2s complement, just add one to the result. For example,Examplea = 3 # 11 in binary b = (a ^ 65535) + 1 print(bin(b))OutputThis will give the output:0b1111111111111101
You can use the del function to delete a specific key or loop through all keys and delete them. For example,my_dict = {'name': 'foo', 'age': 28} keys = list(my_dict.keys()) for key in keys: del my_dict[key] print(my_dict)This will give the output:{}You can also use the pop function to delete a specific key or loop through all keys and delete them. For example,my_dict = {'name': 'foo', 'age': 28} keys = list(my_dict.keys())for key in keys:my_dict.pop(key) print(my_dict)This will give the output:{}
You can put comments like you normally would anywhere in a python script. But note that you can only put single line comments using #. Multiline comments act like strings and you cannot put just a string in between definition of a dict. For example, the following declaration is perfectly valid:testItems = { 'TestOne': 'Hello', # 'TestTwo': None, }But the following is not:testItems = { 'TestOne': 'Hello', """ Some random multiline comment """ }
To set white border to an element, use the border-white class.Add white border − This has white border Above, I have also added a style to set the div element −.mystyle { width: 200px; height: 100px; margin: 10px; background: blue; }Let us see an eample to implement the border-white class in Bootstrap −ExampleLive Demo Bootstrap Example .mystyle { width: 200px; height: 100px; margin: 10px; background: blue; } The following are two Rectangles: This has white border This has orange border
