python多个斐波那契

以下是使用Python编写的多个斐波那契数列的代码示例：

1. 生成前n个斐波那契数列：

def fibonacci_sequence(n):
    a, b = 0, 1
    for i in range(n):
        yield a
        a, b = b, a + b

n = 10
for num in fibonacci_sequence(n):
    print(num)

2. 生成指定范围内的斐波那契数列：

def fibonacci_sequence_range(start, end):
    a, b = 0, 1
    while a <= end:
        if a >= start:
            yield a
        a, b = b, a + b

start, end = 0, 100
for num in fibonacci_sequence_range(start, end):
    print(num)

3. 生成第n个斐波那契数：

def fibonacci_number(n):
    if n <= 0:
        return 0
    elif n == 1:
        return 1
    else:
        return fibonacci_number(n-1) + fibonacci_number(n-2)

n = 10
print(fibonacci_number(n))

4. 生成小于等于n的最大斐波那契数：

def max_fibonacci_number(n):
    a, b = 0, 1
    while b <= n:
        a, b = b, a + b
    return a

n = 100
print(max_fibonacci_number(n))
