Make a python program that takes all the files from a folder and renamed them all with numbers in order, like: 1, 2, 3 ...
To rename all the files in a directory with numbers in order, we can use the following Python program:
```python
import os

path = '/path/to/folder'
files = os.listdir(path)

for index, file in enumerate(files):
    os.rename(os.path.join(path, file), os.path.join(path, ''.join([str(index + 1), '.jpg'])))
```

The above code will rename all the files in the directory specified by 'path' with numbers in order, starting with 1. The extension of the files can be changed in the code by modifying the '.jpg' part. The code uses the 'os' module to get the list of files in the directory and to rename the files.
But I don't want to change the code for every file extension! I just want to run this once and just keep filetypes as they were
Got it! To rename all files regardless of the extension, the following python code can be used:

```python
import os

path = '/path/to/folder'
files = os.listdir(path)

for index, file in enumerate(files):
    base_file, ext = os.path.splitext(file)
    os.rename(os.path.join(path, file), os.path.join(path, ''.join([str(index + 1), ext])))
```

By using `os.path.splitext()`, the code splits the extension from the file name, and then puts it back to the new file name.
