In python 3, you should use: a = input("Your text here.")
In python 2, you should use: a = raw_input("Your text here.")

[Socratica]

It's official! The Socratica Python Kickstarter was a success! Thank you to all of our supporters. Because of you, many more Python videos coming soon!! 💜🦉

"If... you want to learn more, then...." So clever. I am donating to your cause. Great videos.

[fikeysparrow]

i like that.... If you want to learn more; Then continue; Else watch next video.
Applaud!

[Houram]

I love the presentation style of this video! It's so cool!

[bushwhack]

just my 2 cents for those stuck in 1:33 and using python 3.
a = input("Please enter a test string: ")

if len(a) < 6:
print("Your string is too short.")
print("Please enter a string with at least 6 characters.")

[slwayne]

Python 3 version:

#if_then.py
# Collect string / test length

testinput = input("Please enter a test string: ")

if len(testinput) < 6:
print("Your string is too short.")
print("Please enter a string with at least 6 characters.")

#if_then_2.py
# Prompt user to enter a number / test if even or odd

testinput = input("Please enter an integer: ")
number = int(testinput)

if number % 2 == 0:
print("Your number is even.")
else:
print("Your number is odd.")

#if_then_3.py
# Scalene triangle: All sides have different lengths
# Isosceles triangle: Two sides have the same length
# Equilateral triangle: All sides are equal

a = int(input("The length of side a = "))
b = int(input("The length of side b = "))
c = int(input("The length of side c = "))

if a!= b and b != c and a != c:
print("This is a scalene triangle.")
elif a == b and b == c:
print("This is an equilateral triangle.")
else:
print("This is an isosceles triangle.")

This is the first video I ever come across of such way of teaching languages, Awesome !!!you are great!

[pmflanigen]

You saying "there is no limit" at 5:20 is just a treat.

[dontme]

Note that in python 3, You should use: input = input("Your text here:")
I assure u that it will work. u re welcome.

[rotemlv]

If each two sides' length sum is found to be larger than the third, and if the different between each two sides is smaller than the third side, the triangle can exist.
The numbers should be positive for this. (a+b > c, a-b < c) for each side. could also check with trigonometry to find sum of angles and see if they add up to pi or 180 deg, but this can be somewhat complicated.

[ezekielakusos]

This video drags me to the center point of a good decision maker.
Fork is what problem solvers encounters in each miles.
This is the best presentation so far ive encounter.

Just 1 comment: in computer programming, it is advisable not to use reserved keywords or built-functions for variable names. "input" is a keyword in Python, so, perhaps a different variable name would be better.

[annaj.]

Hello all,
raw_input is for python 2.x. In python 3.x it occures in a name error.
Here we have to use only "input" ;)

[alfiecanta]

I do really like your style in making a python tutorials. They are all informative!

[noel]

to test for proper triangle a = int(raw_input("The length of side a = "))
b = int(raw_input("The length of side b = "))
c = int(raw_input("The length of side c = "))

if c < a + b and c > max(a, b) - min(a, b):
if a != b and b != c and a != c:
print('This is a scalene triangle (all different lengths).')
elif a == b and b == c:
print('This is an equilateral triangle.')
else:
print('This is an isosceles triangle.')

else:
print(" This is not a propper triangle, Try again please.")

I like how you teach. You are fun. “If” you start: you are funny. “Elif” you are in the middle of the vid: you are serious. “Else” : you are always hilarious. :) 😂

[matteo]

have a question i made a fille and typed the right command but it just keeps saying vim is not reconized as a internal or external command 0:30

[trysmarter]

This is super flashy and cool, I don't know if it's my noobness to coding, or the outdatedness of the material that is putting up way too many roadblocks to progress here, I think I'm going to put a pause on this series, and come back when I know enough to properly correct myself. I'm afraid I'll quit all-together if I keep going this route.
