Now we will get the data opening the file and putting it into a variable called content:<\/p>\n\n\n\n
Get the content of the csv file<\/h2>\n\n\n\ndef get_csv():\n\twith open(\"colors.csv\") as file:\n\t\tcontent = file.readlines()\n\treturn content<\/pre>\n\n\n\nUsing get_csv se will get the data into colors.csv. We can make it more ‘abstract’ changing it into this, so that is usable for any csv file, instead of the specific one named colors.csv<\/p>\n\n\n\n
def get_csv(file):\n\twith open(file) as file:\n\t\tcontent = file.readlines()\n\treturn content<\/pre>\n\n\n\nIn this case you got to specify the name of the file when you call the function get_csv with:<\/p>\n\n\n\n
content = get_csv(\"colors.csv\")<\/pre>\n\n\n\nIf we want to write more readable code we can also enhance the script with some hints:<\/p>\n\n\n\n
def get_csv(file: str) -> list:\n\twith open(file) as file:\n\t\tcontent = file.readlines()\n\treturn content<\/pre>\n\n\n\nSo now we know that we must pass a parameter that is a string and that the function will return a list out of the file csv. If you wanna be more explicit you can add this:<\/p>\n\n\n\n
def get_csv(csv_filename: str) -> list:\n\t''' return a list with an item for each line of the file '''\n\twith open(csv_filename) as file:\n\t\titemslist = file.readlines()\n\treturn itemslist<\/pre>\n\n\n\nOk, now I thinks is really readable with all the names that have sense and give the idea of what they are made for.<\/p>\n\n\n\n
Creating the dictionary with data we need<\/h2>\n\n\n\n
Now we want to put this data into a dictionary, so that it is easy to use them for our apps (we will use it for a colorpicker app the tutorial of which will be posted in a couple of days or even less).<\/p>\n\n\n\n
def create_dic(content):\n\tcoldic = {}\n\tfor k in content[:5]:\n\t\tid,name,hx,r,g,b = k.split(\",\")\n\t\tname = name.replace(\"\\\"\",\"\")\n\t\tcoldic[name] = hx\n\treturn coldic<\/pre>\n\n\n\nUse the functions<\/p>\n\n\n\n
Now we get the data we need and display them to see what we get.<\/p>\n\n\n\n
content = get_csv(\"colors.csv\")\ndic = create_dic(content)\nprint(*dic.items(), sep=\"\\n\")<\/pre>\n\n\n\n
