快捷導(dǎo)航

基于Python編寫(xiě)一個(gè)根據(jù)姓名測(cè)性別的小程序

更新時(shí)間：2022年03月15日 08:53:25 作者：顧木子吖

這篇文章主要為大家介紹了如何利用Python編寫(xiě)一款根據(jù)中文名能猜測(cè)性別的一款界面化的小程序，文中的示例代碼講解詳細(xì)，感興趣的小伙伴可以了解一下

導(dǎo)語(yǔ)

以前上英語(yǔ)課老師都會(huì)教哪些名字一聽(tīng)就知道是男生的，比如David、Tom、Jerry，然后Angela、Sophia一聽(tīng)就是女生的名字。當(dāng)你以為所有名字一聽(tīng)就可以辨別男女的時(shí)候，你就想錯(cuò)了~就像中文里面“賈凡”，你以為是男生，其實(shí)是女生也說(shuō)不定。這種難分性別的名字

其實(shí)很多呢~為了避免寶寶的性別和提前取好的名字沖突，很多準(zhǔn)媽媽會(huì)給自己的孩子取一個(gè)中性的名字，不管男女都可以用哈哈哈~兩全其美

?每個(gè)女孩子都希望自己的姓名能取的好聽(tīng)一點(diǎn)兒，也不希望經(jīng)常跟男孩子名字撞名吧~想想一個(gè)班里面一個(gè)男生一個(gè)女生名字撞了多尷尬，如果名字偏女孩子一點(diǎn)兒，男生叫這個(gè)名字那可能就尷尬癌都犯了，相反也是！

當(dāng)然，送大家一句經(jīng)典臺(tái)詞搶救一下：“你不尷尬——尷尬的就是別人！“

哈哈哈！那下面就說(shuō)到正題了哈：今天小編教大家編寫(xiě)一款根據(jù)中文名能猜測(cè)性別的一款界面化的小程序呢~

一、準(zhǔn)備環(huán)節(jié)

本文是基于Pyqt5的界面化小程序啦~

1.1 安裝環(huán)境

Python3、Pycharm、pyqt5以及一些自帶滴。

模塊安裝： pip install -i https://pypi.douban.com/simple/ +模塊名

二、準(zhǔn)備素材

素材的話(huà)就是界面化小程序的頭像標(biāo)志以及之前自己爬取準(zhǔn)備的一份百家姓的數(shù)據(jù)csv數(shù)據(jù)。

三、開(kāi)始敲代碼

3.1 導(dǎo)入模塊

import os
import csv
import sys
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *

3.2 定義界面

self.setWindowTitle('諸子百家——姓名猜性別小程序')
        self.setWindowIcon(QIcon('data/3.png'))
        self.setFixedSize(400, 200)
        self.name_label = QLabel('中文姓名:')
        self.male_label = QLabel('男生概率:')
        self.female_label = QLabel('女生概率:')
        self.button = QPushButton('預(yù)測(cè)')
        self.name_edit = QLineEdit()
        self.male_edit = QLineEdit()
        self.female_edit = QLineEdit()
        self.grid = QGridLayout()
        self.grid.setSpacing(12)
        self.grid.addWidget(self.name_label, 0, 0)
        self.grid.addWidget(self.male_label, 1, 0)
        self.grid.addWidget(self.female_label, 2, 0)
        self.grid.addWidget(self.name_edit, 0, 1)
        self.grid.addWidget(self.male_edit, 1, 1)
        self.grid.addWidget(self.female_edit, 2, 1)
        self.grid.addWidget(self.button, 0, 2)
        self.setLayout(self.grid)
        self.button.clicked.connect(lambda: self.predict(self.name_edit.text()))

3.3 預(yù)測(cè)性別

?def predict(self, name):
        def genderprob(name, probs, type_='male'):
            assert type_ in ['male', 'female']
            if type_ == 'male':
                p = self.male_total / self.total
                for c in name:
                    p *= probs.get(c, (0, 0))[0]
            else:
                p = self.female_total / self.total
                for c in name:
                    p *= probs.get(c, (0, 0))[1]
            return p
        for c in name:
            assert u'\u4e00' <= c <= u'\u9fa0'
        male_prob = genderprob(name, self.name_probs, 'male')
        female_prob = genderprob(name, self.name_probs, 'female')
        result = {'male': male_prob / (male_prob + female_prob), 'female': female_prob / (male_prob + female_prob)}
        self.male_edit.setText(str(result['male']))
        self.female_edit.setText(str(result['female']))
        return result

3.4 讀取數(shù)據(jù)

    def readCSV(self, csvpath='freqs.csv'):
        fp = open(csvpath, 'r', encoding='utf-8')
        csv_reader = csv.reader(fp)
        name_freqs = {}
        for idx, row in enumerate(csv_reader):
            if idx == 0: continue
            name_freqs[row[0]] = (row[1], row[2])
        return name_freqs
