# Python Exercise: Get next day of a given date

## Python Conditional: Exercise - 41 with Solution

Write a Python program to get next day of a given date.

Sample Solution:

Python Code:

``````year = int(input("Input a year: "))

if (year % 400 == 0):
leap_year = True
elif (year % 100 == 0):
leap_year = False
elif (year % 4 == 0):
leap_year = True
else:
leap_year = False

month = int(input("Input a month [1-12]: "))

if month in (1, 3, 5, 7, 8, 10, 12):
month_length = 31
elif month == 2:
if leap_year:
month_length = 29
else:
month_length = 28
else:
month_length = 30

day = int(input("Input a day [1-31]: "))

if day < month_length:
day += 1
else:
day = 1
if month == 12:
month = 1
year += 1
else:
month += 1
print("The next date is [yyyy-mm-dd] %d-%d-%d." % (year, month, day))
```
```

Sample Output:

```Input a year: 1974
Input a month [1-12]: 2
Input a day [1-31]: 15
The next date is [yyyy-mm-dd] 1974-2-16.
```

Python: Cache results with decorators

There is a great way to cache functions with decorators in Python. Caching will help save time and precious resources when there is an expensive function at hand.

Implementation is easy, just import lru_cache from functools library and decorate your function using @lru_cache.

```from functools import lru_cache

@lru_cache(maxsize=None)
def fibo(a):
if a <= 1:
return a
else:
return fibo(a-1) + fibo(a-2)

for i in range(20):
print(fibo(i), end="|")

print("\n\n", fibo.cache_info())
```

Output:

```0|1|1|2|3|5|8|13|21|34|55|89|144|233|377|610|987|1597|2584|4181|

CacheInfo(hits=36, misses=20, maxsize=None, currsize=20)```
