从另一个def内部调用def



我想调用另一个def内部的def示例:

def 1(a,b):
Print(a,b)
Def 2 (c,d):
Print(c,d)

我想做的事情就像我们从这样的类中调用一个函数

class().def(variables)

我想做一些类似上面代码的事情类似的东西

def1().def2(variables)

感谢:D

我有这个代码

self.Console.setText(sys.stdout.getvalue())





def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton1.setText(_translate("MainWindow", "PushButton"))






Ui_MainWindow.printer("hi")

QtTest.QTest.qWait(5000)





if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())

我需要调用打印机功能,但我不能

我试图将q文本对象设置为全局对象,但出现错误print hi命令不起作用,因为打印机fumc在另一个功能上

除非返回,否则不能在另一个函数中调用函数。

这意味着,你不能这样做:

def func1(a,b):
print(a,b)
def func2 (c,d):
print(c,d)
func1().func2()

然而,你能做的是:

def func1(a,b):
print(a,b)
def func2 (c,d):
print(c,d)
return func2
func2 = func1()
func2()

至于你为什么要这样做,我不清楚,但如果你必须这样做,这会让你这样做。

如果可能的话,我建议把两者放在一个班里。
