object PyLong_FromString(char *str, char **pend, int base)
|
|
# Return value: New reference.
|
|
# Return a new PyLongObject based on the string value in str,
|
|
# which is interpreted according to the radix in base. If pend is
|
|
# non-NULL, *pend will point to the first character in str which
|
|
# follows the representation of the number. If base is 0, the
|
|
# radix will be determined based on the leading characters of str:
|
|
# if str starts with '0x' or '0X', radix 16 will be used; if str
|
|
# starts with '0', radix 8 will be used; otherwise radix 10 will
|
|
# be used. If base is not 0, it must be between 2 and 36,
|
|
# inclusive. Leading spaces are ignored. If there are no digits,

|
# ValueError will be raised.
