#### List

For example, let's define a variable to be a `list` of `str`.

=== "Python 3.9+"

    Declare the variable, with the same colon (`:`) syntax.

    As the type, put `list`.

    As the list is a type that contains some internal types, you put them in square brackets:

    ```Python hl_lines="1"

            // TODO (donat) verify reported problem details
        }
    }

    @Issue("https://github.com/gradle/gradle/issues/24169")
    def "notation without colon does not suggest using .module"() {
        tomlFile << """[libraries]
my-lib = "org.gradle.test"
"""

        when:
        fails ':help'

        then:

			name:         "windows path no drive",
		},
		{
			goos:         "windows",
			path:         "\\:\\some\\path",
			expectedPath: "\\:\\some\\path",
			name:         "windows path with colon",
		},
	}
	for _, test := range tests {
		if runtime.GOOS == test.goos {
			path := MakeAbsolutePath(test.goos, test.path)
			if path != test.expectedPath {

The Go path is used to resolve import statements.
It is implemented by and documented in the go/build package.

The GOPATH environment variable lists places to look for Go code.
On Unix, the value is a colon-separated string.
On Windows, the value is a semicolon-separated string.
On Plan 9, the value is a list.

If the environment variable is unset, GOPATH defaults
to a subdirectory named "go" in the user's home directory
