python學習筆記(五) 依概率隨機產生姓氏案例

        生活中，不同的姓氏出現的頻率大不相同。如趙、王、李等姓出現頻率很高，而像東方、慕容這樣的複姓卻很少見到，今天我們就來在python中簡單實現一下上述過程。

要求：姓氏全都按行保存在CNames中，越靠後的姓氏越少見。各行數組出現概率比爲20：15：5：2：1，對應行數組爲0-3行，4-8行，9-15行，16-20行，21-25行

CNames.txt文件包含內容如下圖所示：

加載數據

	def load_file():
    text_data=[]
    with open('CName.txt','r',encoding='utf-8') as f:
        data=f.readlines()
        for line in data:
            tmp=line.split(';')
            text_data.append(tmp[:-1])
    return text_data

產生概率行數組

	probability_control=[
	    [0,1,2,3],
	    [4,5,6,7,8],
	    [9,10,11,12,13,14,15],
	    [16,17,18,19,20],
	    [21,22,23,24,25]
	]
	loop=[20,15,5,2,1]
	def probability_line(data:list,ranges:list):
    if len(data)==len(ranges):
        data=data.copy()
        count=0
        for loops in loop:
            for a in range(loops-1):
                data.append(data[count])
            count+=1
        return data
    else:
        print('長度不匹配')

產生隨機姓氏

	import random
	def generator_line(data):
    name=load_file()
    line_combine=data[random.randrange(len(data))]
    line=line_combine[random.randrange(len(line_combine))]
    random_name=name[line][random.randrange(len(name[line]))]
    return random_name

全部代碼：

	import random
	probability_control=[
	    [0,1,2,3],
	    [4,5,6,7,8],
	    [9,10,11,12,13,14,15],
	    [16,17,18,19,20],
	    [21,22,23,24,25]
	]
	loop=[20,15,5,2,1]
	def load_file():
	    text_data=[]
	    with open('CName.txt','r',encoding='utf-8') as f:
	        data=f.readlines()
	        for line in data:
	            tmp=line.split(';')
	            text_data.append(tmp[:-1])
	    return text_data
	   
	def probability_line(data:list,ranges:list):
	    if len(data)==len(ranges):
	        data=data.copy()
	        count=0
	        for loops in loop:
	            for a in range(loops-1):
	                data.append(data[count])
	            count+=1
	        return data
	    else:
	        print('長度不匹配')
	
	def generator_line(data):
	    name=load_file()
	    line_combine=data[random.randrange(len(data))]
	    line=line_combine[random.randrange(len(line_combine))]
	    random_name=name[line][random.randrange(len(name[line]))]
	    return random_name
	
	def main():
	    data=probability_line(probability_control,loop)
	    with open('random_name.txt','w') as f:
	        for i in range(10000):  # 隨機產生10000個姓氏
	            name=generator_line(data)
	            f.write(name+'\n')
	
	if __name__=='__main__':
	    main()
