Some exercises for learning python.
- Rename file
Q1: Write a program that renames all files in a directory and its subdirectories, replacing spaces with underscores. For example, the file "My Program.py" would be renamed to "My_Program.py". Multiple consecutive spaces should be treated as a single space.
Q2: There are some pictures in the directory, and the pictures's name randomly generated. Write a program that renames all pictures in the directory. The new name is the created time of the picture. For example, "2018-01-19_12-34-56.jpg".
Q3: There are some pictures in the directory, and the pictures's name randomly generated. Write a program That renames all pictures in the directory, and the new names are like "1.jpg", "2.jpg", "3.jpg", and so on. If the total number of pictures is more than 10, the new name is like "01.jpg", "02.jpg", "03.jpg", and so on. If the total number of pictures is more than 100, the new name is like "001.jpg", "002.jpg", "003.jpg", and so on. The order of numbers depends on the created time of the picture.
