Reportlabs 写入多个页面作为运输标签（整页）Python

Question

我对使用 Reportlabs 非常陌生，并且正在尝试寻找一种更好的方法来生成如下所示的整页运输标签：

到目前为止，我有这段代码（尽管写得不好）：

import datetime

from reportlab.lib import colors
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas

year = datetime.date.today().year

# IIRNumber = str(int(input("Month (digit): "))) + "-" + str(int(input("Shipment Number (include zero if before 10): ")))
# VMBENumber = "VBME-" + str(year)[-2:] + "-" + str(int(input("Enter VBME Number (last four digits: ")))
# PONUmber = input("Enter PO number or V for Various: ")
IIRNumber = "08-09"
VMBENumber = "VBME-21-1458"
PONUmber = "9185555"

ShipmentNumber = int(input("How many pieces in the shipment?: "))
print(VMBENumber)
print(IIRNumber)
print(ShipmentNumber)


def textobject_demo():

    my_canvas = canvas.Canvas("PDFGenerated.pdf",
                              pagesize=letter)
    # Create text_object
    text_object = my_canvas.beginText()
    # Set text location (x, y)


    # Write a line of text + carriage return
    # Set font face and size
    text_object.setFont('Times-Roman', 12)
    text_object.setTextOrigin(150, 730)

    for i in range(1, ShipmentNumber + 1):

        # Write text to the canvas
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text='To: Voisey Bay Mine Site – EXPANSION PROJECT (VBME)')
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="             C/O Innu Mikun Hangar")
        text_object.textLine(text="             Happy Valley-Goose Bay, NL")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="                     CC0012- " + VMBENumber + " - " + IIRNumber)
        text_object.textLine(text="                     Product Description:" + PONUmber)
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="                         Box " + str(i) + " of " + str(ShipmentNumber))
        text_object.textLine(text="                         Gross Weight: 14 lbs")
        text_object.textLine(text="                         Net Weight: 14 lbs")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="                         Dimensions: 9 L x 9 W x 9” H")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="             Special Storage Instruction: NO")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="")
        text_object.textLine(text="             Attn:   IIR – REDPATH Canada Limited")
        text_object.textLine(text="                         Underground Garage ATTN: Mark / Shawn")
        text_object.textLine(text="")
        my_canvas.drawText(text_object)
        my_canvas.showPage()

    my_canvas.save()


if __name__ == '__main__'
    textobject_demo()

有没有更好的方法？

我正在尝试简化我们使用 python 生成这些 froms 的方式，以复制和粘贴每页的信息

感谢大家的帮助

小家伙

如果有人感兴趣，我就是这样做的：

from reportlab.pdfgen import canvas

po_numbers = []
l_in_in = []
w_in_in = []
h_in_in = []
alpha_letter = []

df = pd.DataFrame(data, columns=['Order', 'L (in)', 'W (in)', 'H (in)', 'Weight (lbs)', 'Letter'])

alpha_or_num = input("Letters or Numbers (L or N)?: ")

for i in df["Order"].dropna():
    po_numbers.append(str(i).replace(".0", ""))
for i in df["L (in)"].dropna():
    l_in_in.append(i)
for i in df["W (in)"].dropna():
    w_in_in.append(i)

    h_in_in.append(i)
for i in df["Letter"].dropna():
    alpha_letter.append(i)
    print(i)
for i in df["Weight (lbs)"].dropna():
    weights.append(i)

number_of_pieces = len(df[df.Order.notnull()])

print(number_of_pieces)
iir_number = "IIR " + input("Enter IIR Number (XX-XX): ")
