The generator is very powerful. If the calculated algorithm is more complex, the "for loop" of the list generation is not realized, and the function can be used to realize it. 比如,著名的斐波拉契数列(Fibonacci),除第一个和第二个数外,任意一个数都可由前两个数相加得到: For example, the f...
The usual solution is to implement Fibonacci numbers using a for loop and a lookup table. However, caching the calculations will also do the trick. First add a @cache decorator to your module: Python decorators.py import functools # ... def cache(func): """Keep a cache of previous fun...
那么将上面函数改造一下,不打印,直接返回n以内的斐波那契数列列表,代码如下: >>> def fib2(n): # return Fibonacci series up to n ... """Return a list containing the Fibonacci series up to n.""" ... result = [] ... a, b = 0, 1 ... while a < n: ... result.append(a) # ...
我们可以创建一个将Fibonacci系列写入任意边界的函数: >>> >>> def fib(n): # write Fibonacci series up to n ... """Print a Fibonacci series up to n.""" ... a, b = 0, 1 ... while a < n: ... print(a, end=' ') ... a, b = b, a+b ... print() ... >>> #...
9. Fibonacci Series Between 0 and 50Write a Python program to get the Fibonacci series between 0 and 50. Note : The Fibonacci Sequence is the series of numbers :0, 1, 1, 2, 3, 5, 8, 13, 21, ... Every next number is found by adding up the two numbers before it.Expected...
For more Practice: Solve these Related Problems: Write a Python program to generate the Fibonacci sequence up to 50 using a while loop. Write a Python program to use recursion to print all Fibonacci numbers less than 50. Write a Python program to build the Fibonacci series up to a given ...
If the caller is a for loop, it will notice this StopIteration exception and gracefully exit the loop. 22、when the variable was not defined within any method. It’s defined at the class level. It’s a class variable, and although you can access it just like an instance variable (...

one of these features is the ability to use the argumentstepto specify a custom increment or difference between consecutive values in the string. Thus allowing to generate a sequence of data with a specific pattern, such as a sequence of prime numbers or a sequence of Fibonacci numbers...
If we combined the functionality of theifstatement and theforloop, we'd get thewhileloop. Awhileloop iterates for as long as some logical condition remains true. Consider the following code example, which computes the initial subsequence of the Fibonacci sequence. (In the Fibonacci series, the...
