Creating Time Series Data Frames

output —DatetimeIndex('2022-01-01', '2022-01-02', '2022-01-03', '2022-01-04',
'2022-01-05', '2022-01-06', 2022-01-07', '2022-01-08', ...

import pandas as pd

df = pd.DataFrame({
  'A': pd.date_range(start='2022-01-01', end='2022-01-31', freq='D').strftime('%Y/%-m/%-d%-H:%M',
  'B': 100,
})

df.info()
print(df)
