Question

flucommands = """
Library:
    CEL:
    &replace EXPRESSIONS:
    MassFlowRate = """

flucommands = flucommands + 0.43 + "[kg s^-1]"

flucommands = flucommands + """
Temp = """

flucommands = flucommands + 843.15 + "[K]"

counttt = 1
while (counttt<=3):
flucommands = flucommands + "PorositySub" + countt 
flucommands = flucommands + " = " + 0.75 + "\n" 
counttt = counttt + 1

我收到错误

＆＃39; flucommands = flucommands +＆＃34; PorositySub＆＃34; + countt＆＃39;错误是期望的缩进块＆＃39;

感谢任何帮助。感谢!!!

这需要缩进：

while (counttt<=3):
    flucommands = flucommands + "PorositySub" + countt 
    flucommands = flucommands + " = " + 0.75 + "\n" 
    counttt = counttt + 1

python使用缩进代替大括号（在某些其他语言中）用于语句块。

如果没有这个，你的while:循环就没有被定义，因此你收到了错误。

请参阅：http://www.tutorialspoint.com/python/python_while_loop.htm和https://docs.python.org/2.3/ref/indentation.html
