文件操作

打开已经并关闭存在的文件：

data = open('C:\example', 'r').read()
print(data)

data_1 = open('C:\小重山','r',encoding = 'utf-8').read()
print(data_1)

data.close()
data_1.close()

创建一个文件：

file = open('C:\小重山2','w', encoding = 'utf-8')
file.write('hello world!')
file.close()

flush

import sys,time
for i in range(30):
    sys.stdout.write('*')
    sys.stdout.flush()
    time.sleep(0.1)
