python基础-实现进度条功能,for和yield实现

实现进度条功能

方法一：简单FOR实现打印进度条功能
for i in range(10):
print("#",end="",flush=True)
time.sleep(0.4)

#方法二,yeild实现复杂进度条功能

def show_process(total):
recive_size=0
current_size=0

while recive_size<total:

if int(recive_size/total*100) >current_size: #进度比现在的大
print("#",end="",flush=True)

current_size=int(recive_size/total*100)
new_size=yield  #中断
recive_size+=new_size

total=10000000
recive_size=0

precess=show_process(total) #调用getnerator
precess.__next__()
while recive_size <total:
recive_size+=10
try:
precess.send(10) #给generotor发送数据，并继续yield后面的执行
except StopIteration as e:
print("100%")
