def port_check(HOST):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
s.connect((HOST, int(22)))
s.shutdown(2)
return True
except:
return False
Here is what the above code is Doing:
1. It’s creating a socket object.
2. It’s trying to connect to the host on port 22.
3. If it can connect, it shuts down the socket.
4. If it can’t connect, it returns false.
days = [“Sunday”,”Monday”,”Tuesday”,”Wednesday”,”Thursday”,”Friday”,”Saturday”] for index,day in enumerate(days): if index >= 0: index += 1 print(index, day) Here is what the above code is Doing: 1. We create a list of days of the week. 2. We use a for loop to iterate through the list. 3. We use the enumerate() function to get the index…
![sys.path[0]](https://myedukit.com/wp-content/uploads/sys.path0_-768x496.jpg)
import sys print(sys.path) Here is what the above code is Doing: 1. We import the sys module. 2. We print the value of sys.path. sys.path is a list of strings that specifies the search path for modules. In simple terms, it is a list of directories where Python will look for modules and packages. When…
func(**{‘type’:’Event’}) # ^ is equivalent to v func(type=’Event’) Here is what the above code is Doing: 1. We are creating a function named func that takes a variable number of keyword arguments. 2. We are using ** to unpack the keyword arguments into a dictionary named kwargs. 3. We are printing the value of kwargs….
import os import shutil os.remove(‘/your/path/to/file.txt’) #removes a file. os.rmdir(‘/your/folder/path/’) #removes an empty directory. shutil.rmtree(‘/your/folder/path/’) #deletes a directory and all its contents. Here is what the above code is Doing: 1. The first line removes a file. 2. The second line removes an empty directory. 3. The third line deletes a directory and all its contents.
import keyboard # using module keyboard if keyboard.is_pressed(‘e’): # if key ‘e’ is pressed print(“you’re holding the E key!”) Here is what the above code is Doing: 1. It’s checking if the key ‘e’ is pressed. 2. If it is, it prints “you’re holding the E key!” 3. If it isn’t, it does nothing. You…
>>df.select_dtypes(include=’object’).columns Index([‘C’, ‘D’], dtype=’object’) Here is what the above code is Doing: 1. df.select_dtypes(include=’object’) – This returns a dataframe with only the object columns 2. .columns – This returns the column names of the dataframe 3. Index([‘C’, ‘D’], dtype=’object’) – This is the output of the above code
