This question already has an answer here:
I am wondering why the following variable is treated like a number?
a = 1_000_000 print (a)
With Python 3.6 (and PEP-515) there is a new convenience notation for big numbers introduced which allows you to divide groups of digits in the number literal so that it is easier to read them.
Examples of use:
a = 1_00_00 # you do not need to group digits by 3! b = 0xbad_c0ffee # you can make fun with hex digit notation c = 0b0101_01010101010_0100 # works with binary notation f = 1_000_00.0 print(a,b,c,f)
print(int('1_000_000')) print(int('0xbad_c0ffee', 16)) print(int('0b0101_01010101010_0100',2)) print(float('1_000_00.0'))
A = 1__000 # SyntaxError: invalid token
