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.

Does python have a double type?

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.

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Python: compiler or Interpreter?Python: compiler or Interpreter?May 13, 2025 am 12:10 AM

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
