Checking Date within Specified Date Range Using Python Code
In a recent programming challenge, the task was to write a Python program that checks if a date exists in a list within a given date range. Here's a solution that uses the built-in Python function .
The programming language used to develop the solution is Python. The program takes a date list and a date range as input. The date range is defined by a start and end date, while the original date list is:
The function is used to check for the presence of any date in the given date range. If any date in the list falls within the given date range, the program returns . Conversely, if no date in the list falls within the given date range, the program returns .
The solution provided uses a loop to iterate through the date list and check each date against the date range. The loop checks each date using conditional statements to determine if it falls within the date range.
Here's a simplified version of the code:
```python def check_date_in_range(dates, start_date, end_date): for date in dates: if start_date <= date <= end_date: return True return False
start_date = datetime.datetime(2020, 1, 1, 0, 0) end_date = datetime.datetime(2020, 12, 31, 0, 0)
print(check_date_in_range(dates, start_date, end_date)) # Returns True ```
It's worth noting that the time complexity for the solution using is O(n) due to looping through the list. Auxiliary space for the solution using is O(1) as no extra space is used.
This solution provides a straightforward and efficient way to check if a date exists in a list within a given date range using Python's function.
