Sample Solution:
Python Code :
import pandas as pd
import numpy as np
df = pd.read_excel('E:\SaleData.xlsx')
print(pd.pivot_table(df,index=["Manager"],values=["Sale_amt"],aggfunc=[np.mean,len]))
Sample Output:
mean len Sale_amt Sale_amt Manager Douglas 29882.000000 8.0 Hermann 30425.708333 12.0 Martha 33749.500000 14.0 Timothy 25446.444444 9.0

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
