flush的用法

认知差别，找了半天打字机和play

结果他是flush ，汗颜

#进度条实例
'''
import sys,time

for i in range(100):
    sys.stdout.write("*")
    sys.stdout.flush()
    time.sleep(0.1)

print('Finished.')
'''

#要比打字速度吗

#import sys,time,os

#os.system("notepad")
import sys,time

str = "要比打字速度吗，来吧，开始吧！！！\n"

f = open('./file_needed/fast_english.txt')

for i in str:
    sys.stdout.write(i)
    sys.stdout.flush()
    time.sleep(0.25)

for i in f.read():
    sys.stdout.write(i)
    sys.stdout.flush()
    time.sleep(0.025)
