之前简单介绍过：基于os库用python批量重命名文件
# open / read 'r'
# f = open('text','r')
# content = f.read()
# print(content)
# f.close()
# # write 'w'
# f = open('text','w')
# f.write("dajidali")
# f.close()
# 写入----》相当于新建文件
f = open('hongda','w')
f.write("jiang")
f.close()
# with 用
with open('hongda','r') as f1,open('text','w') as f2:
content = f1.read()
f2.write(content)
print(content)
# copy
# read write
