When using Python, you will always encounter the use of path switching, such as the test.py under folder test to invoke the Data.txt file under the Data folder: . └──folder ├──data │ └──data.txt └──test └──test.py A method can be added to the data file __init__.py then import data in the test.py can invoke Data.txt file; Another way to manipulate the directory structure with the hel

Types of Python CpythonThe official version of Python, implemented using the C language, is the most widely used, and the CPython implementation converts the source file (py file) into a bytecode file (PYc file) and then runs on the Python virtual machine. JyhtonPython Java implementation, Jython will dynamically compile

FHexadecimal vs. Binary relations:Binary conversion Hex:Binary conversion to 16 binary method is to take four-in-one method, that is, from the decimal point of the binary points to the left (or to the right) every four bits (can not be made up four bits, the left (or rightmost) of the decimal point 0, the conversion)16 Notation of the binary:suffix: H Example: BH represents 16 binary 11Prefix: 0x* Example:0X23 is the Binary conversion Hex:A point four, that is, a hexadecimal number is divided

element# setMySet = Set ([1,2,3,3,3])print myset #Set ([+)];　　　　Three. Python's loops and judgments.Python does not like C # and Java this will put some code snippets with {} expansion, for Python with: number implementation of the parentheses function.Note:print and if are not in the same column, which actually indicates that print is the sub-code of the If column, within the IF {}. It is not clear why this design, but used to the parentheses in C

This has a lapse of time, I can not remember the specific statements, and now summarize.First, get the current file pathSecond, get the previous level file pathHere you can imagine getting the path to your own sibling file, so write:That is to get the parent directory first, and then through the join function to put the sibling directory test in.Third, get all the file names under the current pathGet the data for a list, which is the name of all the f
