(foo) only foo equals Foo.read (), the function of the read function is to read a string from an open file. It is said that some people do not like to read the file!! Why is that? Because: The mechanism of Read () is to read the contents of a file into memory, not meet the needs of everyone So there's a readlines () load all the content into memory once, and split by row, compositing list ReadLines () Foo = open (' Test ', ' r ') SS = Foo.readlines () print (ss) [' a\n ', ' bb\n

Chapter 5-dict objects Similar to the map of C ++ STL in Python, dict is a ing container (key-> value), but the implementation principle is different. Because python uses a large number of structures such as dict (such as the Intese mechanism of string objects) and has high efficiency requirements, Python does not use
