Printing boolean value in Pythom

வினா Language and Input
1

I want to validate the data received from branch offices. They provide totalstockreceivedother,truckstocks,railstocks. I want to validate whether truck stocks and rail stocks add up to the value equal to totalstockreceivedother.So I created another value totalstockreceived and try to print the boolean value.
My Code is as follows

totalstockreceivedother=1000

truckstocks=600

railstocks=400

totalstockreceived=truckstocks+railstocks

if(totalstockreceivedother=totalstockreceived,true,false)

print(boolean(if(totalstockreceivedother==totalstockreceived,true,false)))

It is returning error:SyntaxError: invalid syntax. Maybe you meant ‘==’ or ‘:=’ instead of ‘=’?
Help me.

Hi @Jagadeesan_Ravichand ,

totalstockreceivedother = 1000
truckstocks = 600
railstocks = 400

totalstockreceived = truckstocks + railstocks

if totalstockreceivedother == totalstockreceived:
  print(True)
else:
  print(False)

To check the equality, you should use == (double equalto symbol). Single = symbol will work as assignment.

மேலும் bool மற்றும் Str function மூலமாகவும் bool value ஐ print செய்யலாம் என்றும் அறிந்து கொண்டேன்.

Great!

Also remember, print will implicitly call str to convert everything to string. So,

totalstockreceivedother = 1000
truckstocks = 600
railstocks = 400

totalstockreceived = truckstocks + railstocks

print(totalstockreceivedother == totalstockreceived)

this will also produce same results.

The easier method is:

totalstockreceivedother = 1000

truckstocks = 600
railstocks = 400

totalstockreceived = truckstocks + railstocks

print(totalstockreceivedother == totalstockreceived)

bool operator இல்லாமலேயே print function,bool value ஐ அச்சிடும் நிலையில், வேறு எந்த சூழ்நிலையில் bool பயன்பாடு தேவைப்படும் என விளக்க முடியுமா

Good Question,

In situations, where your function returns a non boolean value. Like numbers, strings, list. In those situation if you need to get a boolean value, then you can perform bool operation.

Numbers: 0 → False; Other than 0 → true.

print(bool(12))
print(bool(0))

Strings: “” → False, Non-Empty Strings → True

print(bool("")) # False
print(bool("parottaSalna")) # True

Similarly to all the data structures, if the list, tuple or dict is empty then it will return false.

Another example,

def check_value():
    value = bool(value)
    if value:
        print("Value is True")
    else:
        print("Value is False")

check_value(None)  # Value is False
check_value(10)  # Value is True

check_value(None) ல் None என்பது Non-empty string தானே. பிறகு எப்படி False என output வரும்?

None is not a string. Its a None type.

So it will result in False.
None is False.
