random.random()用于生成一个随机浮点数: random() -> x in the interval [0, 1). >>> import random >>> random.random() 0.999410896951364 random.uniform(a,b)用于生成一个指定范围内的随机浮点数,a,b为上下限 Get a random number in the range
>>> random.choice("PythonRandomModule")#字符串'P'>>> random.choice(["Delon","is","a","nice","boy"])#列表'a'>>> random.choice(("Tuple1","Tuple2","Tuple3"))#元组'Tuple1' ④random.randint | randint(self, a, b) | Return random integer in range [a, b], including both end...
Python3 range() 函数返回的是一个可迭代对象（类型是对象）函数语法 range(stop)range(start, stop[, step])参数说明：start: 计数从 start 开始。默认是从 0 开始。例如range（5）等价于range（0， 5）;stop: 计数到 stop 结束，但不包括 stop。例如：range（0， 5） 是[0, 1, 2, 3, 4]没有5...
def randint(self, a, b):"Return random integer in range [a, b], including both end points."翻译过来就是返回值是在 [a, b] 区间的随机数（integer类型），其中包括 a和 b。
random_number=randint(1,10)print(random_number)# 输出:1到10之间的随机整数 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 关键点解析: 导入整个模块:使用import module_name。 导入特定函数:使用from module_name import function_name。

random.randint() 语法如下: random.randint(a, b) 语法说明: 该语句相当于random.randint(a, b+1) 返回随机整数 N 满足 a <= N <= b 示例如下: import random for i in range(5): print(random.randint(10,20)) ### 12 15 10 13 13...
Return sends a specified value back to its caller whereas Yield can produce a sequence of values. We should use yield when we want to iterate over a sequence, but don't want to store the entire sequence in memory. import sys # for example when reading a large file, we only care about...
