I have lots of excel files(xlsx format) and want to read and handle them.

For example, file names are ex201901, ex201902, .... 201912. 

Its name is made by exYYYYMM format.

Anyway, to import these files in pandas as an usual case, it's easy.

```
import pandas as pd

df201901 = pd.read_excel(r'C:\\users\ex201901.xlsx)
df201902 = pd.read_excel(r'C:\\users\ex201902.xlsx)
df201903 = pd.read_excel(r'C:\\users\ex201903.xlsx)
df201904 = pd.read_excel(r'C:\\users\ex201904.xlsx)
....
df201912 = pd.read_excel(r'C:\\users\ex201912.xlsx)

```

However, it seem to be a boring and tedius.

In SAS program, I use *Macro()* syntax. But in python, I have no idea how to handle.

Can you help me how to handle the multiple and repeated jobs in easy way, like a *SAS MACRO()*.

Thanks for reading.
