Python common error messages - TypeError- str
TypeError: 'str' object is not callable
Lets run a program to generate the error
class tables:
def __init__(self,w):
# 2.4 Definitions of tables for the FSM
ans = self.T0_r(w)
print "Result = %s" (ans)
def T0_r(self, w):
self.tables_ls()
self.w = w
self.s1_t0_r = self.T0[self.w]
return self.s1_t0_r
def tables_ls(self):
self.T0 = ['0xFF563C6' ,'0x84FF7CF8'
,'0x897788EE' ,'0x8EFB7BF6',
'0xFE2F2FF ' ,'0xBCAF6BD6'
,'0xAA6F6FDE' ,'0xFFC5C591']
def main ():
# Read elemant 4 of the table array by calling class
y = tables(0x4)
main()
Error
Traceback (most recent call last):

print "Result = %s" (ans)
TypeError: 'str' object is not callable
Solution
print "Result = %s" (ans)
Instead of
print "Result = %s" % (ans)
