Python: Print yesterday, today, tomorrow

Python datetime: Exercise - 7 with Solution

Write a Python program to print yesterday, today, tomorrow.

Sample Solution:

Python Code:

# Import the datetime module
import datetime 

# Get the current date using datetime.date.today()
today = datetime.date.today()

# Calculate yesterday's date by subtracting 1 day from today's date using timedelta(days=1)
yesterday = today - datetime.timedelta(days=1)

# Calculate tomorrow's date by adding 1 day to today's date using timedelta(days=1)
tomorrow = today + datetime.timedelta(days=1) 

# Print yesterday's date
print('Yesterday : ', yesterday)

# Print today's date
print('Today : ', today)

# Print tomorrow's date
print('Tomorrow : ', tomorrow)

Output:

Yesterday :  2017-05-05                                                                                       
Today :  2017-05-06                                                                                           
Tomorrow :  2017-05-07  

Explanation:

In the exercise above,

• The code imports the "datetime" module, which provides functionalities to work with dates and times.
• Get Current Date:
• It retrieves the current date using the "datetime.date.today()" method and assigns it to the variable 'today'.
• Calculating Previous and Next Dates:
• It calculates yesterday's date by subtracting one day from the current date ('today') using the "datetime.timedelta(days=1)" function. The result is assigned to the variable 'yesterday'.
• It calculates tomorrow's date by adding one day to the current date ('today') using the "datetime.timedelta(days=1)" function. The result is assigned to the variable 'tomorrow'.
• Finally it prints the calculated dates ('yesterday', 'today', and 'tomorrow') along with their corresponding labels.
