本文实例为大家分享了python+pyqt5编写md5生成器的具体代码，供大家参考，具体内容如下
学了一下pyqt5，写一个小程序来实践一下。
下图是程序界面：
下面是代码：
import hashlib, os, sys
from PyQt5.QtGui import QFont, QIcon
from PyQt5.QtWidgets import (QFileDialog,
QGridLayout, QLineEdit, QTextEdit,QLabel, QWidget, QToolTip,
QPushButton, QApplication)
from PyQt5.QtCore import QCoreApplication
#小文件的处理函数
def get_md5_small(file_path):
md5 = None
if os.path.exists(file_path) and os.path.isfile(file_path):
with open( file_path, 'rb' ) as f:
md5_obj = hashlib.md5()
md5_obj.update( f.read() )
hash_code = md5_obj.hexdigest()
md5 = str(hash_code).lower()
return md5
#大文件的处理函数
def get_md5_big(file_path):
md5 = None
if os.path.exists(file_path) and os.path.isfile(file_path):
with open( file_path, 'rb' ) as f:
md5_obj = hashlib.md5()
while True:
d = f.read(8096)
if not d:
break
md5_obj.update(d)
hash_code = md5_obj.hexdigest()
md5 = str( hash_code ).lower()
return md5
class MainBody(QWidget):
def __init__(self):
super(MainBody, self).__init__()
self.init()
def init(self):
#布局
grid = QGridLayout()
self.setLayout(grid)
grid.setSpacing(10)
#文件路径
self.m_tedit = QTextEdit()
self.m_tedit.setToolTip( u'可以拖拽文件到这里来' )
grid.addWidget(self.m_tedit, 1, 0, 2, 3)
#四个按钮
self.m_select_btn = QPushButton(u'选择文件')
self.m_select_btn.clicked.connect( self.select_func )
self.m_generate_btn = QPushButton(u'生成')
self.m_generate_btn.clicked.connect( self.generate_func )
self.m_clear_btn = QPushButton(u'清空')
self.m_clear_btn.clicked.connect( self.clear_func )
self.m_copy_btn = QPushButton(u'复制')
self.m_copy_btn.clicked.connect( self.copy_func )
grid.addWidget(self.m_select_btn, 3, 0)
grid.addWidget(self.m_generate_btn, 3, 1)
grid.addWidget(self.m_clear_btn, 3, 2)
grid.addWidget(self.m_copy_btn, 5, 1)
#md5的输出区域
self.m_output = QLineEdit()
grid.addWidget(self.m_output, 4, 0, 1, 3)
self.setGeometry(300,300,300,200)
self.setWindowTitle(u"md5生成器")
self.setWindowIcon(QIcon('icon.png'))
self.show()
#选择文件
def select_func(self):
filename, ok = QFileDialog.getOpenFileName(self, "Open file", "C:/Users/Administrator/Desktop")
print(os.path.getsize(filename))
self.m_tedit.setText( filename )
self.m_output.clear()
#生成md5按钮
def generate_func(self):
path = self.m_tedit.toPlainText()
if path.startswith( 'file:///' ):
path = path[8:]
if os.path.exists(path) and os.path.isfile(path):
#200M以上的当作大文件
if os.path.getsize(path) >= 200*1024*1204:
md5 = get_md5_big( path )
else:
md5 = get_md5_small( path )
self.m_output.setText( md5 )
def clear_func(self):
self.m_tedit.clear()
self.m_output.clear()
#复制
def copy_func(self):
clipboard = QApplication.clipboard()
clipboard.setText( self.m_output.text() )
if __name__ == "__main__":
app = QApplication(sys.argv)
mb = MainBody()
sys.exit( app.exec_() )
最后用 pyinstaller 打包成 exe 文件
