how do I write the code to read the previousfile accroding to the timeframe example I want to see the previousfile, obviously 2.50 PM (File Number2)

df1 = pd.read_excel ()
print (df1)

Answer 1

You can get the file names from that path and sort it by modification time and print the last two files.

from pathlib import Path

fnames = Path("Path/of/xlsx files").glob("*.xlsx")
fnames_with_modtime = [(x, x.stat().st_mtime) for x in fnames]
#sort by modification time

fnames_with_modtime.sort(key = lambda x: x[1])

#last modified two files
file1, _ = fnames_with_modtime[-1]
file2, _ = fnames_with_modtime[-2]

df1 = pd.read_excel(file1)
df2 = pd.read_excel(file2)
print(df1)
print(df2)
