如何在不点击任何按钮的情况下将 Python 脚本输出重定向到 PyQT5 GUI 控制台？
How to redirect Python script output to PyQT5 GUI Console, without any buttons clicks?
嘿，我使用相同的旧代码来获取 PyQT5 QTexBrowser GUI 控制台的所有代码输出，但我也在所有新行中获取下一行字符（“\n”）。
代码 URL - pipe the output of sys.stdout to text browser in pyqt
下面是我在上面使用的代码 URL -
class Port(object):
def __init__(self, view):
self.view = view
def write(self, *args):
# self.view.append(str([*args]))
# self.view.append(str(*args).rstrip("\n").lstrip("\n"))
self.view.append(*args)
GUI 控制台输出 -
有什么方法可以从 args 中删除 "\n"，请提出建议。
当我使用下面的行时，我能够看到每个新参数中都有 "\n"。
self.view.append(str([*args]))
带有可见 "\n" 的 GUI 控制台输出（*忽略作为第一个字符的行中的数字 - 这是用户选择输出的一部分。）
然后我尝试了所有可能的方法来删除像 strip(), lstrip() 等，仍然没有成功。
下面是代码的一部分，我如何将 运行 时间输出重定向到 QtextBrowser
self.execution_result = QtWidgets.QWidget()
self.execution_result.setObjectName("execution_result")
self.execution_rslt_saveresult_btn = QtWidgets.QPushButton(self.execution_result)
self.execution_rslt_saveresult_btn.setGeometry(QtCore.QRect(1220, 780, 131, 25))
self.execution_rslt_saveresult_btn.setObjectName("execution_rslt_saveresult_btn")
# ------------------------------------------------------------------------------------------------------#
# Console Output
# ------------------------------------------------------------------------------------------------------#
self.execution_rslt_textbrowser = QtWidgets.QTextBrowser(self.execution_result)
self.execution_rslt_textbrowser.setGeometry(QtCore.QRect(2, 1, 1371, 771))
self.execution_rslt_textbrowser.setObjectName("execution_rslt_textbrowser")
self.execution_rslt_textbrowser.setStyleSheet(
"""QTextBrowser {background-color: #000000;
color: #00FF00;
font: 11pt Courier new;}""")
self.execution_rslt_textbrowser.document().setPlainText(
"-" * 40 + '\n' + " Log starts from below line " + '\n' + "-" * 40)
# ------------------------------------------------------------------------------------------------------#
# Below line is sending run time output to GUI console
# ------------------------------------------------------------------------------------------------------#
sys.stdout = Port(self.execution_rslt_textbrowser)
请任何人建议我应该在此处做什么以从输出行中删除 "\n"。

要删除 flush 属性错误，只需将此覆盖功能添加到您的端口 class：
def flush(self):
pass
已测试！
append方法增加了一个额外的endline，解决方法是插入文本而不添加：
class Port(object):
def __init__(self, view):
self.view = view
def flush(self):
pass
def write(self, text):
cursor = self.view.textCursor()
cursor.movePosition(QtGui.QTextCursor.End)
