Thanks for making this, I really appreciate it!

something that I've been trying to gain a concrete explanation of as I learn the introduction to python and programming in general is how variables are kind of implicitly defined when, for example, you're making the for loop here. While 'fruits' is assigned a value (a list in this case) on the first line, 'fruit' is assigned on the fly within the for loop script. I thought that it's only locally defined, but then I see that subsequent to the for loop, printing 'fruit' prints the last item in the list? Any commentary would help me understand this better.

Your videos are so straight to the point. Watching in 1.5x speed.

1. To print only the last element of the list you can use:
print(fruits[-1])
2. To use for loop without len() you can use:
for i in fruits[::]:
print(i)

I get syntax error on the first else:

fruits = ['apples', 'pears', 'strawberry', 3, 8, 90 ]

for fruit in fruits:
if fruit == 'pears':
print(fruit)
else:
print('not pears')
for x in range(0, 6):
if fruits[x] == 'pears':
print(fruit[x])
else:
print('not a pear')

This video has no dislikes. Let's keep it that way shall we?

I'm having a little trouble distinguishing squared brackets from parenthesis, you need the square brackets in the initial list right?

I just want to print out the strings but not integers in the list, so I tried this:

fruits = ['apple', 'orange', 'banana', 12, 15, 18]

for fruit in fruits:
if fruit != type(int):
print(fruit)
else:
print('not a fruit')

However, it just printed all 6 things out, may I ask what is the problem? Thanks
