Extract Decimal Numbers in Python: 2 Easy Methods

To extract the numbers after the decimal point, you can achieve this by using string slicing or mathematical operations.

Option 1: Method 1 involves utilizing string slicing operations.

num = 3.14159
decimal_part = str(num).split('.')[1]
print(decimal_part)  # 输出：14159

Option 2: Utilize mathematical operations.

num = 3.14159
decimal_part = num - int(num)
print(decimal_part)  # 输出：0.14159

Both of these methods can help you retrieve numbers after the decimal point. The choice of method depends on your specific needs.
