?️? 5. 清空文本框
# 清空三个文本框 def clear_all(): text1.delete('1.0', 'end') text2.delete('1.0', 'end') text3.delete('1.0', 'end')
?️? 6. 正则匹配结果
# 正则匹配 def check_regex(): text3.delete('1.0', 'end') re_text = text1.get('1.0', '1.end') source_text = text2.get('1.0', END) try: pattern = re.compile(f'{re_text}') result = re.findall(pattern, source_text) if result: # 循环输出 for res in result: if res != '': text3.insert(END, res+'\n') else: text3.delete('1.0', 'end') text3.insert('insert', '匹配结果为空') except: text3.delete('1.0', 'end') text3.insert('insert', '匹配失败')
?️? 7. 设置滚动条
# 创建滚动条 scroll2 = Scrollbar(orient=VERTICAL,command=text2.yview) text2.config(yscrollcommand = scroll2.set) scroll2.grid(row=3,column=4, pady=10, sticky=S+W+E+N) # 创建滚动条 scroll3 = Scrollbar(orient=VERTICAL,command=text3.yview) text3.config(yscrollcommand = scroll3.set) scroll3.grid(row=4,column=4, pady=10, sticky=S+W+E+N)
