String Formatting

Formatting Operations

  • 'd'
  • Signed integer decimal.
  • 'i'
  • Signed integer decimal.
  • 'o'
  • Signed octal value.
  • 'u'
  • Obsolete type – it is identical to 'd'.
  • 'x'
  • Signed hexadecimal (lowercase).
  • 'X'
  • Signed hexadecimal (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 lowercase exponential format if exponent is less than -4 or not less than precision, decimal format otherwise.
  • 'G'
  • Floating point format. Uses uppercase exponential format if exponent is less than -4 or not less than precision, decimal format otherwise.
  • 'c'
  • Single character (accepts integer or single character string).
  • 'r'
  • String (converts any Python object using repr().
