创建一个fibo.py
def fib(n): # write Fibonacci series up to n
a, b = 0, 1
while b < n:
print b
a, b = b, a+b
引入这个文件,就可以使用了
>>> import fibo
>>> fibo.fib(100)
1
1
2
3
5
8
13
21
34
55
89
或者
>>> from fibo import fib
>>> fib(100)
1
1
2
3
5

89
或者
>>> from fibo import *
>>> fib(10)

fibo.py
def fib(n):
a,b = 0,1
while b < n:
print b
a,b = b,a+b
if __name__ == "__main__":
import sys
fib(int(sys.argv[1]))
# python fibo.py 50
