篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Python学习第二天相关的知识，希望对你有一定的参考价值。
基本数据类型
Python中一切事物都是对象，对象基于类创建
编码：
Ascii 8位共256个字符
Unicode码，至少16位
Utf-8 如果是数字、字母、字符2个字节，16位来存；汉字用3个字节，24位来存。
转码：
Python内部提供一个sys模块，其中sys.argv用来捕获执行Python脚本传入的参数
#！usr/bin/env python3import sysprint(sys.argv)
F:\py>python improt_argv.py 8000[‘improt_argv.py‘, ‘8000‘]字符串拼接:
Python中的字符串在C语言中体现为一个字数组，每次创建字符串需要在内存中开辟一块连续的空，并且一旦需要修改字符串的话，就需要再次开辟空间，使用“+”号拼接在内存中会重新开辟一块空间，称为万恶的“+”号。

class int(object): """
int(x=0) -> integer
int(x, base=10) -> integer
Convert a number or string to an integer, or return 0 if no arguments
are given. If x is a number, return x.__int__(). For floating point
numbers, this truncates towards zero.
If x is not a number or if base is given, then x must be a string,
bytes, or bytearray instance representing an integer literal in the
given base. The literal can be preceded by ‘+‘ or ‘-‘ and be surrounded
by whitespace. The base defaults to 10. Valid bases are 0 and 2-36.
Base 0 means to interpret the base from the string as an integer literal.
