Let's start :)

Exercise 1

word1 = 'now'
word2 = 'go'
word3 = 'and'
word4 = 'code'
word5 = 'some'
word6 = 'python'

print(f'{word1.title()} {word2} {word3.upper()} {word4} {word5} {word6.upper()} ')

Exercise 2

rython = 'Now go and code some Python'

print(rython.split())

Exercise 3

my_fav_language = 'Python rocks'

print(my_fav_language.rstrip(' rocks'))

Exercise 4

rython = 'Now go and code some PYTHON'

print(rython.lstrip('Now go and code some '))

Exercise 5

rython = 'Now go and code some python'

if 'python' in rython:
    print(rython.upper())

Did you do all the exercises first? You didn't cheat did you!?

Alright go ahead. Here are the answers.

Exercise 1

word1 = 'now'
word2 = 'go'
word3 = 'and'
word4 = 'code'
word5 = 'some'
word6 = 'python'

print(f'{word1.title()} {word2} {word3.upper()} {word4} {word5} {word6.upper()} ')
>>>Now go AND code some PYTHON

Exercise 2

rython = 'Now go and code some Python'

print(rython.split())
>>>['Now', 'go', 'and', 'code', 'some', 'Python']

Exercise 3

my_fav_language = 'Python rocks'

print(my_fav_language.rstrip(' rocks'))
>>> Python

There is something I want to clarify when using the 'strip', 'rstrip' or 'lstrip' method. You might think that the word 'rocks' is stripped, but this function strips the characters passed through the function. So the letters 'r', 'o', 'c', 'k', 's'.

Now you might say why wasn't the output 'Pythn', because we passed an 'o'. That is because the function stops as soon as it encounters a character that wasn't passed. In this case it works from right to left. Stripping each character in the process. Then encounters 'n' and stops, because we didn't pass the character 'n'.

I know there are better functions for this result, but just wanted to show how this functions works.

Exercise 4

rython = 'Now go and code some PYTHON'

print(rython.lstrip('Now go and code some '))
>>> PYTHON

Exercise 5

rython = 'Now go and code some python'

if 'python' in rython:
    print(rython.upper())
>>> NOW GO AND CODE SOME PYTHON
