Python中random模块用法实例分析

import randomx = random.randint(1,4);y = random.choice(['appale','banana','cherry','durian']);print(x,y);

l=[ ]while True:  name=input("请输入一个名字:")  if name!='':    l.append(name)  else:    breakprint(l);

'''求1到100直接所有整数的和'''x=range(1,101,1)sumi=0for i in x:  sumi+=iprint(sumi)

u1='''求阶乘的一般方法'''print(u1)def jc(n):  s=1  for i in range(1,n+1):    s*=i  return sn = input("n! usage:<number>:")h = jc(int(n))print(h)

求阶乘的一般方法n! usage:<number>:5120

u2='''通过递归实现阶乘'''print(u2)def jch(n):  if(n==1):    return 1  else:    return n*jch(n-1)un=input("input n:")s=jch(int(un))print("n! is ",s)

通过递归实现阶乘input n:5('n! is ', 120)
