作业19

1、检索文件夹大小的程序，要求执行方式如下

python3.8 run.py 文件夹

import os
import sys

file = sys.argv[1]
num = 0
def get_size(name):
    global num
    if os.path.isfile(name):
        num += os.path.getsize(name)
    elif os.path.isdir(name):
        abs = os.path.abspath(name)
        for i in os.listdir(abs):
            i = os.path.join(abs,i)
            get_size(i)


get_size(file)
print(num)

2、明天上午日考：随机验证码、模拟下载以及打印进度条、文件copy脚本

# --------------------------验证码--------------------------
import random


def code_maker(size=4):
    code = ""
    for i in range(size):
        s1 = str(random.randint(0, 9))
        s2 = chr(random.randint(65, 90))
        code += random.choice([s1, s2])
    return code


print(code_maker(6))

# --------------------------进度条--------------------------
import time


def pro(rate):
    if rate > 1:
        rate = 1
    percent = int(100 * rate)
    res = "*" * int(percent / 2)
    time.sleep(0.2)
    print("\r[{:<50}]{}%".format(res, percent), end="")

    
    

file_size = 55555
speed = 1024
down = 0
while down <= file_size:
    time.sleep(0.2)
    down += speed
    pro(down / file_size)

# --------------------------copy--------------------------
import sys

file1 = sys.argv[1]
file2 = sys.argv[2]


def copyer(file1,file2):
    with open(file1, "rb") as f1, open(file2, "wb") as f2:
        res = f1.read()
        f2.write(res)



copyer(file1,file2)
