QuantConnect.Parse

Bases: Object

Provides methods for parsing strings using CultureInfo.InvariantCulture

date_time_exact 

date_time_exact(value: str, format: str) -> datetime

date_time_exact(
    value: str,
    format: str,
    date_time_styles: DateTimeStyles,
) -> datetime

Signature descriptions:

  • Parses the provided value as a System.DateTime using System.DateTime.ParseExact(string,string,IFormatProvider) with the specified format and CultureInfo.InvariantCulture

  • Parses the provided value as a System.DateTime using System.DateTime.ParseExact(string,string,IFormatProvider) with the specified format, date_time_styles and CultureInfo.InvariantCulture

decimal 

decimal(value: str) -> float

decimal(value: str, number_styles: NumberStyles) -> float

Signature descriptions:

  • Parses the provided value as a decimal using CultureInfo.InvariantCulture

  • Parses the provided value as a decimal using the specified number_styles and CultureInfo.InvariantCulture

long 

long(value: str) -> int

long(value: str, number_styles: NumberStyles) -> int

Signature descriptions:

  • Parses the provided value as a long using CultureInfo.InvariantCulture

  • Parses the provided value as a long using CultureInfo.InvariantCulture and the specified number_styles

try_parse 

try_parse(
    input: str, value: Optional[timedelta]
) -> Tuple[bool, timedelta]

try_parse(
    input: str,
    date_time_style: DateTimeStyles,
    value: Optional[Union[datetime, date]],
) -> Tuple[bool, Union[datetime, date]]

try_parse(
    input: str,
    number_style: NumberStyles,
    value: Optional[float],
) -> Tuple[bool, float]

try_parse(
    input: str,
    number_style: NumberStyles,
    value: Optional[int],
) -> Tuple[bool, int]

Signature descriptions:

  • Tries to parse the provided value with TryParse as a System.TimeSpan using CultureInfo.InvariantCulture.

  • Tries to parse the provided value with TryParse as a System.DateTime using the specified date_time_style and CultureInfo.InvariantCulture.

  • Tries to parse the provided value with TryParse as a double using the specified number_style and CultureInfo.InvariantCulture.

  • Tries to parse the provided value with TryParse as a int using the specified number_style and CultureInfo.InvariantCulture.

try_parse_exact 

try_parse_exact(
    input: str,
    format: str,
    time_span_style: TimeSpanStyles,
    value: Optional[timedelta],
) -> Tuple[bool, timedelta]

try_parse_exact(
    input: str,
    format: str,
    date_time_style: DateTimeStyles,
    value: Optional[Union[datetime, date]],
) -> Tuple[bool, Union[datetime, date]]

Signature descriptions:

  • Tries to parse the provided value with TryParse as a System.TimeSpan, format string, TimeSpanStyles, and using CultureInfo.InvariantCulture

  • Tries to parse the provided value with TryParse as a System.DateTime using the specified date_time_style, the format format, and CultureInfo.InvariantCulture.
