What's the difference

Question

I've seen some codes whereby true or false is interchanged using the values 1 and 0. Mostly i get confused as to what answer i must choose, so i just want clarity maybe with a code example of how to differentiate between the two

Answer 1

# Standard is using True False keywords, if it is in language, rather than 1 or 0

# python
x = 10
print (x == x) # True

# but some times is useful use 0 for false

a = "variable x = " #not empty string
b = "" # empty string

if ( len(a) ):
x = x+1
print(a + str(x) ) # print it

if ( len(b) ): # print nothing, because length b is 0 (and 0 is evaluated as False)
x = x+1
print(b + str(x) )

print( x ) # 11
