Just return the variable from your first funtion and capture it in the second:

def func1():
    a= 5
    print(a)
    return a
def func2(a):        
    print(a)

a = func1()
func2(a)

Here you have the live example

If what you want is to update a variable within your pyqt app you can use @Devesh answer

Define a outside the function.

a = 5

def func1():
    print(a)

def func2():        
    print(a)

func1()
func2()

Output:

5                                                                                                                                     
5

Remember

  • not best practice
  • does only work for read access to a

Just define both functions in a class, and make a as an attribute.

class A:

    def __init__(self, a):
        self.a = a

    def func1(self):
        self.a= 5
        print(self.a)

    def func2(self):
        print(self.a)


obj = A(4)
obj.func2()
obj.func1()

The output will be.
