Python: Next bigger number by rearranging the digits of a given number
Python Lambda: Exercise-25 with Solution
Write a Python program to create the next bigger number by rearranging the digits of a given number.
Sample Solution:
Python Code :
def rearrange_bigger(n):
#Break the number into digits and store in a list
nums = list(str(n))
for i in range(len(nums)-2,-1,-1):
if nums[i] < nums[i+1]:
z = nums[i:]
y = min(filter(lambda x: x > z[0], z))
z.remove(y)
z.sort()
nums[i:] = [y] + z
return int("".join(nums))
return False
n = 12
print("Original number:",n)
print("Next bigger number:",rearrange_bigger(n))
n = 10
print("\nOriginal number:",n)
print("Next bigger number:",rearrange_bigger(n))
n = 201
print("\nOriginal number:",n)
print("Next bigger number:",rearrange_bigger(n))
n = 102
print("\nOriginal number:",n)
print("Next bigger number:",rearrange_bigger(n))
n = 445
print("\nOriginal number:",n)
print("Next bigger number:",rearrange_bigger(n))
Sample Output:
Original number: 12 Next bigger number: 21 Original number: 10 Next bigger number: False Original number: 201 Next bigger number: 210 Original number: 102 Next bigger number: 120 Original number: 445 Next bigger number: 454

Python: Tips of the Day
Creates a dictionary with the same keys as the provided dictionary and values generated by running the provided function for each value:
Example:
def tips_map_values(obj, fn): ret = {} for key in obj.keys(): ret[key] = fn(obj[key]) return ret users = { 'Owen': { 'user': 'Owen', 'age': 29 }, 'Eddie': { 'user': 'Eddie', 'age': 15 } } print(tips_map_values(users, lambda u : u['age'])) # {'Owen': 29, 'Eddie': 15}
Output:
{'Owen': 29, 'Eddie': 15}
