Pandas: Create a yearly time period from a specified year and find the properties of this period

Pandas Time Series: Exercise-32 with Solution

Write a Pandas program to create a yearly time period from a specified year and display the properties of this period.

Sample Solution:

Python Code :

import pandas as pd
ytp = pd.Period('2020','A-DEC')
print("Yearly time perid:",ytp)
print("\nAll the properties of the said period:")
print(dir(ytp))

Sample Output:

Yearly time perid: 2020

All the properties of the said period:
['__add__', '__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__radd__', '__reduce__', '__reduce_ex__', '__repr__', '__rsub__', '__setattr__', '__setstate__', '__sizeof__', '__str__', '__sub__', '__subclasshook__', '__unicode__', '__weakref__', '_add_delta', '_from_ordinal', '_maybe_convert_freq', '_typ', 'asfreq', 'day', 'dayofweek', 'dayofyear', 'days_in_month', 'daysinmonth', 'end_time', 'freq', 'freqstr', 'hour', 'is_leap_year', 'minute', 'month', 'now', 'ordinal', 'quarter', 'qyear', 'second', 'start_time', 'strftime', 'to_timestamp', 'week', 'weekday', 'weekofyear', 'year']

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")
