We use theforloop that runs ten times and in which with every iteration we increment the valuecounterusingcounter++, which is a shorthand format ofcounter = counter + 1. To print the value ofcounterwe create a functionprintMsg()that prints thecounter. ...

Theenumerate()function adds a counter to an iterable and returns it as an enumerate object. This can be particularly useful when you need both the index and the value of each item in the list. Example: cities = ["New York", "Los Angeles", "Chicago", "Houston"] ...
Master Python for data science and gain in-demand skills. Start Learning for Free Assigning functions to variables To kick us off we create a function that will add one to a number whenever it is called. We'll then assign the function to a variable and use this variable to call the func...
Often something physical, such as a Geiger counter or electrostatic noise, where the results are turned into random numbers. We do not need true randomness in machine learning. Instead we can use pseudorandomness. Pseudorandomness is a sample of numbers that look close to random, but were ...
A for loop implements the repeated execution of code based on a loop counter or the loop variable. For loops are used when the number of iterations is known in advance. This is the structure of a basic for loop in Python: for[Temporary variable]in[sequence]: [do something] ...
