Module osyspyrt.util
General utility functions.
Functions
def group(a, *ns)def hexdump(data)def is_integer(value)-
Return true if the given string consists of one or more digits, 0-9. This differs from built-in functions which recognize other characters that Unicode designates as digits, and it does not allow for whitespace.
def join(a, *cs)def lowest_set(val)-
Return the lowest bit set in the given value.
Parameters
val:int- A value > 0.
Returns
int- The lowest bit set. 0 for the least significant bit.
Raises
ValueError if val == 0 def signed_bytes(value)-
Return the minimal signed, 2's complement representation for the given value. For zero, this will be a bytes object of length 1.
Parameters
value:int
Returns
bytes
def tbcd_bin_to_str(value)-
Convert a TBCD binary representation to a TBCD character string, following 3GPP 29.002.
Parameters
value:bytesorbytearray
Raises
ValueError if the not a valid TBCD binary representation.
def tbcd_digit_to_char(digit)-
Convert a TBCD digit to TBCD char, following 3GPP 29.002. 0xF is converted to empty string. ValueError is raised if digit is not between 0x0 and 0xF.
def tbcd_str_to_bin(value)-
Convert the given TBCD character string to binary, following 3GPP 29.002.
Returns
bytearray
def unsigned_bytes(value)-
Return the minimal unsigned representation for the given value. For zero, this will be a bytes object of length 1.
Parameters
value:int- A value >= 0
Returns
bytes
