Integer
In Python programming, integer is an integer mathematical sense, including positive integers, negative integers and zero, and it is the number of bits is arbitrary. Depending on the method of representation can be divided into:
Binary integer
octal integer
decimal integer
hexadecimal integer
floating point
Float decimals in a mathematical sense, by the left of the decimal integer and fractional right side of the composition.
plural
Complex in the mathematical sense, the real and imaginary part, using j or J represents an imaginary unit. When the presentation is a complex, may be real and imaginary portions I would like to add, such as 2.67 + 12.5j
Arithmetic
In Python programming, using integer arithmetic operators and calculating the difference, product, quotient like:
Comparison operation
Comparison operation, also known as relational operators for comparing the relationship between the left and right worthy of size, phase, etc., if the result is true, returns True, otherwise False.
Boolean
basic type
In Python, only two boolean values: True (true) and False (false). In the process of writing code, all objects can be the true value of the test, which is only about several cases the value obtained is False:
False or None
numbers zero, or an imaginary number including 0, 0.0 0
empty columns (including strings, lists, tuples, dictionaries)
custom object instance of the object bool method returns False or len method returns 0
logic operation
In Python programming, the logic element includes, or non-
Assignment Operators
In Python programming, using an equal sign (=) or other objects for assignment to a variable, such as:
. 1
2
. 3
X = 12 is
Y = 23 is
Z = Y + X
replication
on may be derived from the assignment of special symbols, such as:
Basic Input Output
print()
print () output for any content that you want to export.
input()
input () to enter anything you want to enter.
