## variables #### What is a variable? >A variable is like a container. We can give the variable a name, use it to store the data, read it, or change it. It is often used in actual programming. #### Create variable >Click the Create variable option, enter the name of the variable, click OK to create >

#### Using variables >For example: assign the variable initial value A=6, and add the variable 2 after one second. >

## operation #### Function Description >There are some basic arithmetic blocks in Math, such as "addition, subtraction, multiplication and division". >

* __constant__ Fill in any number and connect to other objects for assignment * __Common operation__ Add data on both sides of the expression to add, subtract, multiply and divide power * __Surplus__ Add data on both sides of the expression to make the remainder * __Special number judgment__ Add a value to set whether the judgment is true (for example, whether it is odd or even or prime), if it is true, it is True, otherwise it is False. * __Array calculation__ Summing an array, calculating the maximum or minimum, the average, etc. * __round__ Rounding off decimals or going to the bottom * __advance operation__ Find trigonometric functions, absolute values, etc. * __convert to int__ Convert the value to an integer * __convert to float__ Convert values to floating point numbers #### Instructions >Add data to both sides of the expression, assign the expression to a variable or other object, and get the result. >

## random #### Function Description >When making games or animations, we sometimes need some random elements, and Random can generate random numbers according to our needs. >

* __random fraction__ Randomly generate a number between 0 and 1 each time it is executed * __random integer__ Specify a random range, each time it is executed, randomly generate an integer in the range #### Instructions >Set a random range with a constant and assign a random intger to a variable >

## map #### Function Description >Map is another variable container model that can store any type of object. >

* __creat map__ Create key-value pairs of map. * __map clear__ clear key-value. * __map contain key__ Confirm if there is a key in map * __get ken in map__ Get the value of Specified key. * __in map add key value__ Add key-value in map. * __in map set key value__ change the value of key in map. * __in map delete key__ Delete specified key #### Instructions >Add a create map to create a map, add some elements to the map, Specify keywords and values >

## array __________________________ #### Function Description >If the variable is a container, the array is a collection of many containers. We can assign values to any of the variables in the array. >

* __length of__ Measure the length of the array (ie the number of elements in the array) * __X is empty__ Determine whether an array is empty. When it is established, the expression is True, otherwise it is False. * __in list find__ Array index, indexed positive or reverse specified element * __create empty list__ Add a value to set whether the judgment is true (for example, whether it is odd or even or prime), if it is true, it is True, otherwise it is False. * __create list with__ Customize an array * __in list get__ Get the index value of an index element * __in list get sub-list from__ Set an index to the specified value in the array * __icreat list with item repeated times__ Create an array and use the element to repeat a certain number of times to fill * __reverse__ Array in reverse order * __in list set as__ Set an index to the specified value in the array * __make list from text with delimiter__ Create an array from text, using a separator #### Instructions >Add a create list to create an array, add some elements to the array, call elements iteratively or by using other methods >

## JSON #### Function Description >JSON (JavaScript Object Notation) is a lightweight data exchange format that is easy for people to read and write. >

* __dumps to json__ Encode Python objects into JSON strings. * __loads json__ Decode an encoded JSON string into a Python object. #### Instructions >Creat a map and turn it into json format >

## TEXT #### Function Description >Use these blocks for text processing and screen display. >

* __" "__ Assign text or String * __to UPPER CASE__ Convert text to uppercase or lowercase. * __in text get letter#__ Get the specified character from the text. * __count in__ Find the number of occurrences of specific characters. * __is empty__ Returns whether it is empty text. * __length of__ Return text length. * __print__ Print text. * __replace with in__ Replace text. * __trim spaces from both sides__ Remove spaces from both sides of the string. * __Convert to str__ Convert other types to strings. * __" "+__ Text merging. * __decode__ Decode the string in the encoding format specified by encoding. * __encode__ Encodes the string in the encoding format specified by encoding. * __Reduce to decimal places__ Retain the specified number of decimal places. #### Instructions > >
