【python基础操作实例】（4）——文本进度条、天天向上

文本进度条

##文本记录条V1
import time
scale = 10
print("------执行开始------")
for i in range(scale+1):
    a='*'*i
    b='.'*(scale-i)
    c=(i/scale)*100
    print("{:^3.0f}%[{}->{}]".format(c,a,b))
    time.sleep(0.1)
print("------执行结束------")

##文本记录条V2
import time
for i in range(101):
    print("\{:3}%".format(i),end="")
    time.sleep(0.1)

##文本记录条V3  [^1]
import time
scale = 50
print("执行开始".center(scale//2,"-"))
start=time.perf_counter()
for i in range(scale+1):
    a='*'*i
    b='.'*(scale-i)
    c=(i/scale)*100
    dur=time.perf_counter() - start
    print("/r{:^3.0f}%[{}->{}]{:.2f}s".format(c,a,b,dur),end='')
    time.sleep(0.1)
print("执行结束".center(scale//2,"-"))

[^1] : V3要在cmd命令指示符下运行

天天向上
