In Python, there are three main data types, each corresponding to different scenarios: 1. Numeric types 2. Sequence types 3. Hash types. Within these three main data types, there are also many subcategories.
# First category: Numeric types
# Contains three subcategories: Integer type
# What is an integer? An int consists of digits from 0-9, all of which are called integers.
# Is there a concept of negative numbers? Yes.
b = 10000
print(b)
print(type(b)) # <class 'int'># Floating-point type: float is the decimal in everyday life. Any number with a decimal point is a floating-point number.
a = 1314.0
print(a)
print(type(a)) # <class 'float'># Boolean type: bool is used to determine truth values. One is called true, and the other is called false.
# The Boolean type is a keyword.
# True represents 1, and False represents 0. Note the capital letter.
a = True
b = False
print(a)
print(type(a)) # <class 'bool'>
print(b)
