        image.svg(f"{lastname}_{firstname}.svg", scale="5")

createQRCode()

我有一个 CSV 文件，其中包含多名员工。我想从这个文件中为每个员工生成一个 Vcard QR 码。不幸的是，扫描 QRCode 时仅检索到 URL。

不幸的是，我没有意识到这个错误，因为我对 Python 缺乏经验。我将非常感谢您的帮助!

由于您使用的是 Python 多行字符串，因此不需要包含换行符、额外的引号和缩进。请尝试以下操作:

import pyqrcode
import pandas as pd

def createQRCode():
    df = pd.read_csv("havas.csv")

    for index, values in df.iterrows():
        lastname = values["lastname"]
        firstname = values["firstname"]
        title = values["title"]
        phone = values["phone"]
        email = values["email"]
        website = values["website"]
        org = values["org"]
        street = values["street"]
        city = values["city"]
        p_code = values["p_code"]
        country = values["country"]

        data = f'''BEGIN:VCARD
N:{lastname};{firstname};
FN:{lastname}+{firstname}
TITLE:{title}
TEL;TYPE=work,VOICE:{phone}
EMAIL;WORK;INTERNET:{email}
URL:{website}
ORG:{org}
ADR;TYPE=work,PREF;;;{street};{city};{p_code};{country}
VERSION:3.0
END:VCARD'''

        image = pyqrcode.create(data)
        image.svg(f"{lastname}_{firstname}.svg", scale="5")

createQRCode()

这将创建以下二维码:

您可以执行以下操作以避免需要额外的变量:

import pyqrcode
import pandas as pd

def createQRCode():
    df = pd.read_csv("havas.csv")

    for index, v in df.iterrows():

        data = f'''BEGIN:VCARD
N:{v['lastname']};{v['firstname']};
FN:{v['lastname']}+{v['firstname']}
TITLE:{v['title']}
TEL;TYPE=work,VOICE:{v['phone']}
EMAIL;WORK;INTERNET:{v['email']}
URL:{v['website']}
ORG:{v['org']}
ADR;TYPE=work,PREF;;;{v['street']};{v['city']};{v['p_code']};{v['country']}
VERSION:3.0
END:VCARD'''

        image = pyqrcode.create(data)
        image.svg(f"{v['lastname']}_{v['firstname']}.svg", scale="5")

createQRCode()
