【原创源码】【Python】PyQt5Json格式文本与字典格式文本相互转换
python中的字典格式是可以使用单引号， 在线的json格式化不支持单引号，所以写了个相互转换的pyqt5小例子（作为练习）。最近刚学pyqt5，不足的地方敬请见谅。
import sys, jsonfrom PyQt5.QtWidgets import (QWidget, QApplication, QHBoxLayout, QVBoxLayout, QPushButton, QTextEdit, QLabel,
QMessageBox)
class JsonToDict(QWidget):
def __init__(self, parent=None):
super(JsonToDict, self).__init__(parent)
self.initUI()
def initUI(self):
self.setGeometry(300, 300, 600, 300)
self.setWindowTitle('JsonToDict')
json_label = QLabel('json文本')
self.json_text_edit = QTextEdit(self)
dict_label = QLabel('dict文本')
self.dict_text_edit = QTextEdit(self)
json_layout = QHBoxLayout()# 将label和textEdit横向布局
json_layout.addWidget(json_label)
json_layout.addWidget(self.json_text_edit)
dict_layout = QHBoxLayout()
dict_layout.addWidget(dict_label)
dict_layout.addWidget(self.dict_text_edit)
json_btn = QPushButton('json_to_dict')
json_btn.clicked.connect(self.json_click)# 添加点击事件
dict_btn = QPushButton('dict_to_json')
dict_btn.clicked.connect(self.dict_click)# 添加点击事件
clear_btn = QPushButton('清空')
clear_btn.clicked.connect(self.clear_click)# 添加点击事件
btn_layout = QHBoxLayout()# 将button横向布局
btn_layout.addWidget(json_btn)
btn_layout.addWidget(dict_btn)
btn_layout.addWidget(clear_btn)
overall_layout = QVBoxLayout()# 整体竖向布局
overall_layout.addLayout(json_layout)
overall_layout.addLayout(dict_layout)
overall_layout.addLayout(btn_layout)
self.setLayout(overall_layout)
self.show()
def json_click(self):
json_content = self.json_text_edit.toPlainText()
try:
self.dict_text_edit.setText(str(json.loads(json_content)))
except Exception as e:
QMessageBox.critical(self, "错误", "输入有误!")
def dict_click(self):
dict_content = self.dict_text_edit.toPlainText()
try:
self.json_text_edit.setText(json.dumps(eval(dict_content)))
except Exception as e:
QMessageBox.critical(self, "错误", "输入有误!")
def clear_click(self):
self.json_text_edit.clear()
self.dict_text_edit.clear()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = JsonToDict()
sys.exit(app.exec_())
json与dic有啥区别吗，没搞懂
