1. The content of the file is as follows, the title is: name, gender, age, salary
egon male 18 3000alex male 38 30000wupeiqi female 28 20000yuanhao female 28 10000
Requirements:
Take out each record from the file and put it into the list. Each element of the list is {'name':'egon','sex':'male','age ':18,'salary':3000}
- According to the list obtained by 1, take out the information of the person with the highest salary
- According to 1 List, take out the information of the youngest person
- According to the list obtained by 1, map the name of each person’s information to the form of initial capital letters
- According to the list obtained by 1, Filter out the information of people whose names start with a
- Use recursion to print the Fibonacci sequence (the sum of the first two numbers gets the third number, such as: 0 1 1 2 3 4 7… )
- A list with many levels of nesting, such as l=[1,2,[3,[4,5,6,[7,8,[9,10,[11,12,13] ,[14,15]]]]]]], use recursion to fetch all the values
