Variables - Python | Lesson 3 (Free Coding Bootcamp)
Free Coding Bootcamp - Go from Zero to Software Engineer
This Bootcamp will follow the roadmap covered in this video
• How to become a software engineer with no ...
In this lesson, we learn about variables and how it can be used to store a value.
To assign a value to a variable, we use an equal sign:
ex) myName = "Vincent"
There are 2 styles of coding: (Camel Case is the most used)
Camel Case: all words joined together, where each subsequent word's first letter is capitalized.
ex) myNameIs, theBigBrownFox
Snake Case: replace spaces with underscores
ex) my_name_is, the_big_brown_fox
There are many types for values, in this video we talk about 4 of them:
Strings: Sequence of characters
ex) "Hello World", "Cash Money $$$!@#@#@"
Integers: Any non decimal number
ex) 1, 0, -1
Floats: Any decimal number
ex) 3.14, 12.32, 123123213.1
Booleans: Either True or False
Pro Tip: If you don't know what something is, just print it!
If you don't know what the value is for a variable, you can print it:
myName = "Vincent"
print(myName)
You can also get the type of the variable or value with:
type(...)
ex)
myName = "Vincent"
print(type(myName))
print(type(123))
