Python has five standard data types: Numbers (Numbers) String (String) List (List) Tuple (Tuple) Dictionary (Dictionary)
Recommended Manual:Python basic introductory tutorial
The data types belonging to the collection type include lists, tuples and dictionaries.
Numbers
The numeric data type is used to store numerical values.
They are immutable data types, which means that changing the numeric data type will allocate a new object.
When you specify a value, a Number object is created:
var1 = 1 var2 = 2
The del statement deletes references to some objects. The syntax is:
del var1[,var2[,var3[....,varN]]]]
Pass Use the del statement to delete references to single or multiple objects. For example:
del var1 del var1, var2
Four different number types: int (signed integer) long (long integer [can also represent octal and hexadecimal]) float (floating point)complex (plural)
float (floating point)
Floating point numbers are used to handle real numbers, that is, numbers with decimals. Similar to the double type in C language, it occupies 8 bytes (64 bits), of which 52 bits represent the base, 11 bits represent the exponent, and the remaining bit represents the symbol.
