 ###### What I want to achieve
The overall goal of this exercise is ：

• Read the data in the file , And store in the form of patient list ; Each patient will be represented by a dictionary , With three keys ："name", "weight" and "height".

• Calculate the... For each patient BMI（ Body mass index ）, And the average number of patients BMI; Test which patients are normal , Which are not .

• Write the result to another file .

The first 1 part ： Import data and put it into the correct data structure

Write a import_lignes function , This function takes the file name as an argument and returns the line list of the file , String list , Each element of the list corresponds to a line of the file . Remember to execute return Close the file before .

Write a function separe , It will be one line （ character string ） As a parameter , And return the dictionary corresponding to the patient in this line . So , Please use the separate provided to you （ That's ok ） Function and returns a list of three strings , The list is obtained by following the space separator . Before storing them in a dictionary , Consider converting weight and height to floating .
Example ：
separe ("Liliane 62 1.67 \ n") return ['Liliane', '62', '1.67'].
separe( "Liliane 62 1.67 \ n" ) Must return {'name': 'Liliane', 'weight': 62.0, 'height': 1.67}
Write a list_patients_from_nom_fichier function , This function takes the file name as an argument , And return the patient list corresponding to the file （ Each of these patients is represented by a dictionary ）.
The first 2 part ： Processing data

Write a function imc , It will the patient （ Dictionaries ） As a parameter , And return to his BMI Round to two decimal places （ remember round (number, 2) The existence and function of ）.BMI The calculation is as follows ：BMI = weight /（ Size 2）.
Write a function imc_moyen , It takes the patient list as a parameter , And return the patient's average BMI, Round to two decimal places .
Write a list_names_patients_en_corpulence_normale function , This function takes the patient list as a parameter , And return to include BMI A list indicating the names of patients with normal obesity , in other words BMI Whether in 18.5 and 25 Between （ Include ）.
The first 3 part ： Write the results to a file

Warning ：Caseine The operation of does not allow you to keep the changes made by the program to the file ： At the end of the run or evaluation , Everything will be reset to zero . therefore , To test this part , You need to choose from the following options ：

Or work in your spare time （ See the opening paragraph ）, Then upload your submission
Or use For you display_console (file_name) function , This function allows you to display the contents of the file whose name is passed as a parameter to the console （ Please refer to the use example in the main program ）.
Write function produire_chaine Accept the patient's parameters , The patient returns a string consisting of the patient's name , Followed by a space , Followed by... Rounded to two decimal places BMI, Followed by a newline .
Write a function ecrite_imc , It takes the name of the patient list and the target file as parameters , And write... In the file ：
For every patient , One line contains their names , Then their BMI, Separate... With spaces （ Remember to use the production string function ）,
And then we write “Average BMI:”, This is followed by the average of patients BMI, Round to two decimal places .
then , We write “ The name of a patient of normal size ：”, And then go back , Then the names of patients with normal body size （ One name per line ）
You can refer to data -results1.txt File to see an example of the expected results （ The data used in this example comes from data1.txt file ）.
Write function traitement_complet_donnees Take the file name containing the data as the parameter , Then write the file name of the result and complete data processing （ in other words , He reads , Processing data , And write the results according to the instructions given in the previous question ）. You can refer to results-data1.txt File to view the information about complete_data_processing （“data1.txt”、“data-results1.txt”） What should be produced by the call of .
