Document Summary

To change the value of a specific item, refer to the index number: Change the second item: thislist = ["apple", "banana", "cherry"] thislist[1] = "blackcurrant" print(thislist) To change the value of items within a specific range, define a list with the new values, and refer to the range of index numbers where you want to insert the new values: Change the values "banana" and "cherry" with the values "blackcurrant" and. "watermelon": thislist = ["apple", "banana", "cherry", "orange", "kiwi", "mango"] thislist[1:3] = ["blackcurrant", "watermelon"] print(thislist) If you insert more items than you replace, the new items will be inserted where you specified, and the remaining items will move accordingly: Change the second value by replacing it with two new values: thislist = ["apple", "banana", "cherry"] thislist[1:2] = ["blackcurrant", "watermelon"] print(thislist) Note: the length of the list will change when the number of items inserted does not match the number of items replaced.

Mosh is a software engineer with two decades of experience and I 've taught over 3 million people how to code. He has designed this Python course for anyone who wants to learn Python. In this tutorial I 'm going to show you how to download and install Python on your computer. You will learn how to use Python in machine learning or artificial intelligence. All the materials you 're going to learn in this course will apply to the latest version of Python as well. At the time of recording this video the latest. version is python 3. 7. 2. Chances are in the future , when you are watching this tutorial there is a newer version of. Python available. The first time we run pycharm we 're going to get this warning because this is an application that we download from the internet. So let 's go ahead and open it every time you open it, click on create new project. Make sure that base interpreter is set to Python 3. Mac computers come with an older installation of Python, that 's Python 2. It 's considered legacy which means it 's no longer maintained or supported. So by convention, all Python files should have this py extension.

In this Python tutorial , we 're gong to take this program to the next level and make it more interesting. So I 'm going to show you how to draw a dog hair. As part of this tutorial you will learn how Python code gets executed and you will also learn about a few programming terms. In the future as you learn more Python you 'll be able to build applications that have a graphical user interface. With this piece of code we can draw 10 asterisks on the terminal. Python interpreter tries to execute line 4 when it executes line 4. It will evaluate the code that we put in between parenthesis. and before the parenthesis , add a space , once again , add an asterisk , space , 10. So let 's run this program one more time , there you go. Are you excited to learn Python and get started on this career path ? If you are, I would encourage you to make a commitment and spend 2 hours every day practicing python. Use the comment box below and let me know why you are learning Python , what do you want to do with it ? What 's your dream job ? I would love to hear your story.

Python interpreter executes our code line by line from the top. On the second line we can update the value of this price variable , so we can reset it to a new value like 20. On line 2, we can define another variable called rating and set it to number 4. 9. Now note that Python is a case sensitive language. Python is sensitive to lower case and upper case letters. In this tutorial, I 'm going to show you how to receive input from the user. So we 're going to write a small program that asks the user 's name and then we 'll print a greeting message customized for that user. In Python we also have functions for common tasks such as printing messages, receiving input , and so on. Mosh has created a cheat sheet with summary notes to review the materials in this course. The link is below this video. So I have done my best to create the best possible Python course on Youtube. And I really appreciate it if you support my hard work by liking this video and sharing it with others.

“Finger exercise: Use the tabular method to implement a dynamic programming solution that meets the specification

def make_change(coin_vals, change):
"""coin_vals is a list of positive ints and coin_vals[0] = 1
change is a positive int,
return the minimum number of coins needed to have a set of
coins the values of which sum to change. Coins may be used
more than once. For example, make_change([1, 5, 8], 11)
should return 3."""

Part (b) [3 MARKS] Complete the function body according to its docstring description. You will be marked only on the parts that need to be different from (a). def count_letter_case_mutate (L): " (list of list of str) -> None Type Precondition: each str in L is non-empty and contains only alphabetic characters Replace each item in L with a two-item tuple in which the first item is the number of words in the list at the corresponding index of L that start with a lowercase letter and the second item is the number of words in the list at the corresponding index of L that start with an uppercase letter >>> data = [['apple', 'Banana'], ['PeAr'], [], ['PEACH', 'aprICot', 'plum']] >>> count_letter_case_mutate (data) >>> data [(1, 1), (0, 1), (0, 0), (2, 1)]
