# Pandas Data Series: Get the day of month, year, week, week number

## Pandas: Data Series Exercise-28 with Solution

Write a Pandas program to get the day of month, day of year, week number and day of week from a given series of date strings.

Sample Solution :

Python Code :

``````import pandas as pd
from dateutil.parser import parse
date_series = pd.Series(['01 Jan 2015', '10-02-2016', '20180307', '2014/05/06', '2016-04-12', '2019-04-06T11:20'])
print("Original Series:")
print(date_series)
date_series = date_series.map(lambda x: parse(x))
print("Day of month:")
print(date_series.dt.day.tolist())
print("Day of year:")
print(date_series.dt.dayofyear.tolist())
print("Week number:")
print(date_series.dt.weekofyear.tolist())
print("Day of week:")
print(date_series.dt.weekday_name.tolist())
``````

Sample Output:

```Original Series:
0         01 Jan 2015
1          10-02-2016
2            20180307
3          2014/05/06
4          2016-04-12
5    2019-04-06T11:20
dtype: object
Day of month:
[1, 2, 7, 6, 12, 6]
Day of year:

## Python: Tips of the Day

Function argument unpacking in Python.

Example:

```def tips_func(x, y, z):
print(x, y, z)

tuple_val = (2, 0, 2)
dict_val = {'x': 3, 'y': 2, 'z': 1}
tips_func(*tuple_val)
tips_func(**dict_val)
```

Output:

```2 0 2
3 2 1
```
