Transmission DoorIdea: Classic DP problem, I come to water a water, see the data range should be able to know this is a multidimensional DP, we can set F (I,J,k,L,m) I walked the first card with J, the 2nd card with K, the 3rd card with L, the 4th card with the maximum score after M. But we found that this transfer, not only the memory is not open, and the transfer time will be timed out, what to do, we found that the five number is not independent, you can know 4 for 5, so we can si

A string composed of FT is given. f Represents Forward, t represents turn, and the initial direction is 1. After turning, F changes from 1 to-1 (or-1 to 1) For example, the value of ftfffffff is 3. Given N, you must perform n operations (Change F to T or change t to F) to find how far forward from the original place (absolute value) You can search to solve this problem. For each trip, we can choose Continue in the current direction Or change the direction. In a rough estimation, the m

tables, translation tables are converted through the Maketrans method. Deletechars--a list of characters to filter in the string.Translate is a one by one mapping of characters. Each character will be replaced with the corresponding character as soon as it appears.Replace is a string substitution, and the string is replaced as a whole. The two string parameter lengths of replace can be different.Thezfill(width) method returns a string of the specified length, the original string is right-ali

1. VariablesIn other programming languages, when a variable is assigned a value to a name, the value is stored in memory, and the name is called a variable.In Python, it's a bit different, it's more like putting a name on top of a value, so you can say that Python has no variables.34= a + bprint (c)2. Places to note when using variables:You need to assign a value to the its first before using the variable.Variable names can include letters, numbers, and underscores, but variable names cannot beg

1. What is BIFBif is a built-in function, English is all called build-in-function3. Is there a difference between "FISHC" and "FISHC"?There's a difference, he's two different strings.The difference between 4.= and = == Assign a value in Python, that is, assign a value to the variable. = = represents equal to5 What is the meaning of stitching?Stitching can be easily understood in Python as a concatenation of two of the same types.Hands-on program1.Name = input ( " Please enter your name:")print("

1. Use of flowchart.In the early stages of writing a program, you can try to write a flowchart, understand the logical sequence, realize the function, judge the condition, etc.2. Built-in functionsBIF = = Built-in-function, querying the built-in functions in Python, you can use code:Dir (__builtins__)3. For a function that is not clear, you can learn about functions by using Help (function).4. The game source code in the classroom:Print("...................... I love you, the union ......... ...
