The first word of the statement starts with thekeyword “for”which signifies the beginning of the for loop. Then we have theiterator variablewhich iterates over the sequence and can be used within the loop to perform various functions The next is the“in” keywordin Python which tells the ...

Use=to assign a variable in Python Assignment in Python is pretty simple on its face, but there's a bit of complexity below the surface. For example, Python's variables arenot buckets that contain objects:Python's variables are pointers. Also you canassign into data structuresin Python. ...
We can change the value of a variablemultiple timesin our code. We can assign a value in one type and then we can change it also to another data type. For example, firstly we can assign a string value to a variable and then we can change it as list type by assigning a list. ...

The Python subprocess module is for launching child processes. These processes can be anything from GUI applications to the shell. The parent-child relationship of processes is where the sub in the subprocess name comes from. When you use subprocess, Python is the parent that creates a new chil...
