What is "0b" in the output of this code and can it be excluded from the output ?

Question

print(bin(10))
print(bin(20))
output: 0b1010
0b10100

Answer 1

Shantanu ,

binary representation can also be done by using string interpolation with f-string. this sample is from the python documentation:

print(f'{14:#b} - {14:b}') # 'b' is the format specifier for binary

# result: '0b1110 - 1110'

so we can decide if we are using the prefix '0b' or not.

[EDITED] added a sample
to get the binary representation stored in a variable, we can use:

res= f'{14:b}'

Answer 2

0b indicates that it number is binary representation. You could simply print only the string from the 2nd index on.
