Afor loopin Python is a loop that iterates through code in its body for a set amount of times until a condition is met. This is helpful in repetitive instances where a user needs to perform the same task a large number of times; or when a user needs to iterate through asequence. Th...
We go over the list of words with aforloop. When the iteration is over, we print the "Finished looping" message which is located in the body following theelsekeyword. $ ./list_loop_for2.py cup star falcon cloud wood door Finished looping Python list loop with enumerate Theenumeratefunctio...
For loop in Python, just like any other language, is used to repeat a block of code for a fixed number of times. For loop is yet another control flow statement since the control of the program is continuously transferred to the beginning of the for loop to execute the body of the for...

Decorators can provide a nice mechanism for caching and memoization. As an example, look at a recursive definition of the Fibonacci sequence: Python >>> from decorators import count_calls >>> @count_calls ... def fibonacci(num): ... if num < 2: ... return num ... return fibon...
The Python language has basic features such as while loop control structures and a general-purpose list data type, but interestingly, no built-in array type. The NumPy library adds support for arrays and matrices, plus some relatively simple functions such as array search and array sort. The ...
