Print (' A: ', self.a, ' b: ', self.b, ' Cssa: ', testcss.cssa)

def define_a (self):

SELF.C = 19

if __name__ = = ' __main__ ':

# TC = TESTCSS ()

# Tc.info ()

# tc.color = ' Red '

# Print (tc.color)

# TC = TESTCSS ()

# TCA = Testcss ()

# TC.A = 100

# TC.B = 200

# Tc.info ()

# Tca.info ()

# TC = TESTCSS ()

# tc.define_a ()

# Print (tc.c)

TC = TESTCSS ()

Tc.info ()

TCA = Testcss ()

Tc.info ()

Testcss.cssa = 0

Tc.info ()

Tca.info ()
