Python | sympy.trailing() method

With the help of sympy.trailing() method, we can count the number of trailing zero digits in the binary representation of a given number, i.e. determine the largest power of 2 that divides that number.

Syntax: trailing(n) Parameter: n - It denotes the number for which the largest power of 2 that divides that number is determined. Returns: Returns the largest power of 2 that divides the given number.

Example #1: Python3

# import trailing() method from sympy
from sympy.ntheory.factor_ import trailing
 
n = 64
 
# Use trailing() method 
trailing_n = trailing(n) 
     
print("The largest power of 2 that divides {} is 2^{}.".
      format(n, trailing_n))

Output:

The largest power of 2 that divides 64 is 2^6.

Example #2: Python3

# import trailing() method from sympy
from sympy.ntheory.factor_ import trailing

n = 130

# Use trailing() method 
trailing_n = trailing(n) 
    
print("The largest power of 2 that divides {} is 2^{}.".
      format(n, trailing_n))

Output:

The largest power of 2 that divides 130 is 2^1.
