Python Reportlab multiple lines

Question

我正在尝试将我的磁盘状态写入pdf。问题是它不能写多行:每个字母的文本都是垂直的。

import subprocess
from reportlab.pdfgen import canvas
p = subprocess.Popen('df -h', stdout=subprocess.PIPE, shell=True)
(disk, err) = p.communicate()
print disk
def hello(disk):
            height= 700
            c = canvas.Canvas("diskreport.pdf")
            c.drawString(200,800,"Diskreport")
            for line in disk:
                    c.drawString(100,height,line.strip()) 
                    height = height - 25
            c.showPage()
            c.save()
hello(disk)

Answer 1

不是在数据中的行上循环，而是在字符上循环。例:

>>> data="""a
... b
... line 3"""
>>> # this will print each character (as in your code)
... for line in data: print line
... 
a

b

l
i
n
e
3
>>> 
>>> # split into lines instead
... for line in data.split('n'): print line
... 
a
b
line 3
>>>

那么在你的代码中你添加.split('n') to your for ' -循环来产生这个:

for line in disk.split('n'):
