I have this:
g_c = 0
class TestClass():
global g_c
def run(self):
for i in range(10):
g_c = 1
print(g_c)
t = TestClass()
t.run()
print(g_c)
how can I actually modify my global variable g_c?
By declaring it global
inside the function that accesses it:
g_c = 0
class TestClass():
def run(self):
global g_c
for i in range(10):
g_c = 1
print(g_c)
The Python documentation says this, about the global
statement:
The global statement is a declaration which holds for the entire current code block.
