Returns:

Bool: True if the paths are equal and False otherwise.

__eq__(self, other: StringSlice[origin]) -> Bool

Returns True if the two paths are equal.

Args:

  • ​suffix (Self): The suffix to append to the path.

Returns:

Self: A new path with the suffix appended to the current path.

__truediv__(self, suffix: StringSlice[origin]) -> Self

Joins two paths using the system-defined path separator.

Args:

  • ​suffix (StringSlice): The suffix to append to the path.

Returns:

Self: A new path with the suffix appended to the current path.

__itruediv__​

__itruediv__(mut self, suffix: StringSlice[origin])

Joins two paths using the system-defined path separator.

Args:

  • ​suffix (StringSlice): The suffix to append to the path.

__str__​

Formats this path to the provided Writer.

Args:

  • ​writer (T): The object to write to.

__fspath__​

__fspath__(self) -> String

Returns a string representation of the path.

Returns:

stat_result: A stat_result object containing information about the path.

Raises:

lstat​

lstat(self) -> stat_result

Returns the lstat information on the path. This is similar to stat, but if the file is a symlink then it gives you information about the symlink rather than the target.

Returns:

stat_result: A stat_result object containing information about the path.

Raises:

If the operation fails.

exists​

exists(self) -> Bool

Returns True if the path exists and False otherwise.

expanduser​

expanduser(self) -> Self

Expands a prefixed ~ with $HOME on posix If environment variables are not set or the path is not prefixed with ~, returns the path unmodified.

    assert_true(p.expanduser() == Path.home())
except e:
    print(e)

Returns:

Self: The expanded path.

Raises:

If the operation fails.

home​

static home() -> Self

Returns $HOME on posix. If environment variables are not set it returns ~.

Examples:

from pathlib import Path

    assert_true(p.expanduser() == Path.home())
except e:
    print(e)

Returns:

Self: Path to user home directory.

Raises:

If the operation fails.

is_dir​

is_dir(self) -> Bool

from pathlib import Path

try:
    assert_true(Path.home().is_dir())
except e:
    print(e)

Returns:

Bool: Return True if the path points to a directory (or a link pointing to a directory).

is_file​

is_file(self) -> Bool

Returns True if the path is a file and False otherwise.

Examples:

from pathlib import Path

try:
    assert_false(Path.home().is_file())
