How to use regex, switch and trim on python to retrieve a value in a file?


I have a file with this format:

Description 10.01.1
;
;     Find the information here
;
University
    National Cantoon University
Status
    National
Administrator visible
    Disable
    *Enable
Start Edu Fair Event
    Event Only
    *Event and invite user
    Event and staff
Permanently Disable
    *No
    Yes
Order
    Year 2021/Jan-Dec(14543043643)

    Year 2022/Jan-Dec(56486565465)

I would like to get the value of each key. for the example, I want to get the value of Status which is National If the value have more than one, then I need to get all the values, example, I need to get the value of Permanently Disable which is *No and Yes . I have done this in PowerShell, I use regex and trim. But now I need to use it in Python. I am new in python, anyone can help me, I really appreciated. Thank you so much

function info
{
    Param($Path, $Values)
    $name = $false
    switch -regex -file $Path
    {
        $Values{ $name = $true; continue }
        '^\s' { if ($name) { $_.Trim() }}
        '^\S' { if ($name) { return }}
    }
}

Solution

  • with open('text.txt', 'r') as f:
        text = f.read()
    
    d = dict()
    key = ""
    
    # iterate line by line
    for line in text.split('\n')[1:]:
        # skip empty line
        try:
            # skip header
            if line[0] == ';':
                continue
            # check whether first character is space
            # no --> key
            if not line[0].isspace():
                key = line
                d[key] = list()
                # print("key: ", line)
            # yes --> value
            else:
                # remove space
                d[key].append(line.strip())
                # print("value: ", line.strip())
        except:
            continue
    

    Output:

    >>> print(d)
    {
     'University': ['National Cantoon University'], 
     'Status': ['National'], 
     'Administrator visible': ['Disable', '*Enable'], 
     'Start Edu Fair Event': ['Event Only', '*Event and invite user', 'Event and staff'], 
     'Permanently Disable': ['*No', 'Yes'], 
     'Order': ['Year 2021/Jan-Dec(14543043643)', 'Year 2022/Jan-Dec(56486565465)']
    }
