# Constants

# The mathmatical constant of pie 3.141592.... up to the available precision math.e

# The mathmatical constante = 2.718281.... up to the available precision

# 'd' Signed integer decimal 'Signed integer decimal 'o' Signed octal value 'u' Obsolete type - it was identical to 'd' 'x' Signed hexadecimal (lowercase) 'X' Signed hexidecimal (uppercase) 'e' Floating point exponential format (lowercase) 'E' Floating point exponential format (uppercase) 'f' Floating point decimal format 'F' Floating point decimal format 'g' Floating point format. Uses the lowercase exponential format if the exponent is less than -4 or not less than precision, otherwise it uses the decimal format

# 'G' Floating point format. Uses the uppercase exponential format if the exponent is less than -4 or not less than precision, otherwise it uses the decimal format

# 'c' Single character (accepts either integer or single character string) 'r' String (converts any Python object using repr()) 's' String (converts any Python object using str()) '%' No argument is converted, adds a % character in the end result
