Python3 file文件基礎操作

Python3 file文件基礎操作，文章內容包含了文件的創建，讀取等基礎操作。閒話少說，直接看代碼：

#讀文件
import os
filePath = os.path.join(os.getcwd() ,'subdict','a.txt' )
file = open(filePath,'r+') #讀＋寫
print(file)
txt = file.read()
file.write('python')
print(txt)

#變量直接被釋放
with open(os.path.join(os.getcwd(),'subdict','a.txt' ),'a+') as fp:
    txt = fp.read()
    print(txt)
    pass

#讀取二進制文件
content = ' '
with open((os.getcwd() + os.sep + '1565145725.jpg'),'rb') as fp:
    content = fp.read()
    pass
print(content)

#複製
with  open((os.getcwd() + os.sep + '1565145725(1).png'),'wb') as fp:
    fp.write(content)
    pass

運行結束，會在當前目錄生成相應的文件。
