I have some time series data where I am attempting to create separate dataframes in Pandas that will be a 0 or 1 based on if the index is a particular day of the week and another for a particular time.
For example I can make up some data with:
import pandas as pd
import numpy as np
from numpy.random import randint
#time = pd.date_range('6/28/2013', periods=2000, freq='5min')
#df = pd.Series(np.random.randint(100, size=2000), index=time)
rng = pd.date_range('10/9/2018 00:00', periods=5, freq='6H')
df = pd.DataFrame({'Random_Number':randint(1, 10, 5)}, index=rng)
df.head()
And if I am doing this correctly I can create a dataframe named Tuesday
that will be a 1
if the day = Tuesday else a 0
#The day of the week with Monday=0, Sunday=6
df['Tuesday'] = np.where(df.index.dayofweek == 1, 1, 0)
df.head()
What I am struggling with (In excel I can do with embedded if else statements) is creating a dataframe called occupied
if the time is in between 7AM & 5PM. Any tips help, thanks in advance!
df['Occupied'] = np.where(df.index.hour > 7 & df.index.hour < 17, 1, 0)
df.head()
This code errors out with a type error that I am not sure what to do about:
TypeError: unsupported operand type(s) for &: 'int' and 'Int64Index'
You are missing the ()
np.where((df.index.hour > 7) & (df.index.hour < 17), 1, 0)
Out[157]: array([0, 0, 1, 0, 0])
You can use pd.DataFrame.eval
:
df['Occupied'] = df.eval('7 <= index.dt.hour < 17').astype(int)
print(df)
