# Example_2

str = '100'

print("int('100') with base 2 = ", int(str, 2))
print("int('100') with base 4 = ", int(str, 4))
print("int('100') with base 8 = ", int(str, 8))
print("int('100') with base 16 = ", int(str, 16))

Output :

int('100') with base 2 = 4
int('100') with base 4 = 16
int('100') with base 8 = 64
int('100') with base 16 = 256

Hi

I just started learning python language and came across this example which I don't understand how the output is achieved for the above mentioned example. (4,16,64,256)

Hello, this is something with bases. We are using base 10, but that choice is arbitrary, so there are other ways to "count". What you are seeing are the other ways to "count" of expressing 100 in base 10.
100 = 10 * 10
2 base 2 = 10 base 10, so 2 * 2 = 4 = 100
4 base 4 = 10 base 10, so 4 * 4 = 16 = 100
8 base 8 = 10 base 10, so 8 * 8 = 64 = 100
16 base 16 = 16 base 16, so 16 * 16 = 256

And there you go.

Sorry if this confuses you, but this is a really mathematical thing. Search it up on bing or google to learn more.
