The FizzBuzz is a famous beginner problem that is often used to start learning a new programming language. Compared to Simple Hello World, the FizzBuzz requires the usage of Loop and If check. The usual text-book solution to FizzBuzz is (in Python) as follows:
1 2 3 4 5 6 7 8 9 10 11 12 13 | class Solution: def solve(self, n): ans = [] for i in range(1, n + 1): if i % 3 == i % 5 == 0: ans.append("FizzBuzz") elif i % 3 == 0: ans.append("Fizz") elif i % 5 == 0: ans.append("Buzz") else: ans.append(str(i)) return ans |
class Solution:
def solve(self, n):
ans = []
for i in range(1, n + 1):
if i % 3 == i % 5 == 0:
ans.append("FizzBuzz")
elif i % 3 == 0:
ans.append("Fizz")
elif i % 5 == 0:
ans.append("Buzz")
else:
ans.append(str(i))
return ansThis isn’t Pythonic at all, with Python, you can do this in one-liner using the list comprehension:
1 2 3 4 | class Solution: def solve(self, n): return ["Fizz" * (i % 3 == 0) + "Buzz" * (i % 5 == 0) or str(i) for i in range(1, n + 1)] |
class Solution:
def solve(self, n):
return ["Fizz" * (i % 3 == 0) +
"Buzz" * (i % 5 == 0) or str(i) for i in range(1, n + 1)]Here you can use the multiply operator to repeat a string pattern n times in Python. This well serves the purpose of concatenating the Fizz and Buzz when it is mod by both 3 and 5 (which is 15).
The OR operator defines the other cases when the number is not a multiple of 3, 5 or 15.
