我正在尝试将我的磁盘状态写入pdf。问题是它没有写多行: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)
答案 0 :(得分:1)
您没有循环遍历数据中的行,而是遍历字符。例如:
>>> 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
>>>
因此,在您的代码中,您为`-循环添加.split('\n') to your
来生成此代码:
for line in disk.split('\n'):
