Python log10

The Python log10 math function calculates the logarithmic value of a given number of base 10. This log10 function is more accurate than math.log(x, 10). The syntax of the Python math log10 Function is


Number: A valid numeric expression and

  • If the number argument is a positive number, the function returns the output.
  • If the number argument is a Zero or a Negative number, it returns ValueError.
  • And if it is not a number, it returns TypeError.

Python log10 Function Example

The Python log10 Function calculates the logarithmic value of a given number of base 10. In this example, We find the base 10 logarithmic value of different data types and display the output.

  1. Within the first two statements, We used the Python log10 Function directly on Positive integer and Decimal values.
  2. Next two statements, We used it on Tuple and List items. If you observe the above Python screenshot, this Math function calculates the logarithm value of base 10.
  3. In the next statement, We tried it directly on multiple values
  4. Next, We tried on the String value, and it returns TypeError: a float is required.
  5. We tried on Negative value, and it is returning ValueError: math domain error.
  6. Last, We tried on Zero value. It is returning ValueError: math domain error. Please refer to the logarithm article to understand the log function.
import math

Tup = (1, 2, 3, -4 , 5) # Tuple Declaration
Lis = [-1, 2, -3.5, -4 , 5] # List Declaration

print('Logarithm value of Positive Number = %.2f' %math.log10(1))
print('Logarithm value of Positive Decimal = %.2f' %math.log10(2.5))

print('Logarithm value of Tuple Item = %.2f' %math.log10(Tup[2]))
print('Logarithm value of List Item = %.2f' %math.log10(Lis[4]))

print('Logarithm value of Multiple Number = %.2f' %math.log10(2 + 7 - 5))
print('Logarithm value of String Number = ', math.log10('Hello'))
