## r表示读 rb表示读二进制 file_object = open('test.py','r')try:    file_text=file_object.read()finally:    file_object.close()print file_text ## 可以直接用for循环遍历文件每行file_input= open('test.py', 'r')try:    for line in file_input:        print linefinally:    file_input.close() ## 或者使用readlines读取每行file_input = open('test.py','r')try:    i=0;    while( i <= 0):        i=i+1        chunk = file_input.readlines()        print(chunk)finally:    file_input.close()

 

## w 表示写文件 w+ 写追加 wb 写二进制 infile = open('test.py','r')outfile = open('log.txt','w+')try:    for line in infile:        outfile.write(line)finally:    infile.close()    outfile.close()
