问题描述

大家好吗


我想知道如何在python中声明一个变量名称那个

它又是一个变量

在bash shell中我会写如下:


for x in seq 1 3`

do

M $ i =材料(x)#Material是一个python类

完成


为什么我需要这个?因为我有一个python模块,迫使我构建

a变量名为Period,它应该有一个变量名称

summands(取决于x的值)


#让我们说x = 3,然后周期定义是

周期=板坯(材料1(12.5)+材料2(25)+材料3(12.5) )#Slab是一个

python类


我不知道如何自动化任何x的最后一段代码


谢谢

Hello to everybody

I would like to know how to declare in python a "variable name" that
it is in turn a variable
In bash shell I would wrote sthg like:

for x in `seq 1 3`
do
M$i=Material(x) #Material is a python class
done

Why I need this? Cause I have a python module that obliges me to build
a variable called Period, which should have a variable name of
summands (depends on the value of x)

#Let''s say x=3, then Period definition is
Period=Slab(Material1(12.5)+Material2(25)+Material 3(12.5)) #Slab is a
python class

I dont know how to automatize last piece of code for any x

thank you

Marcos

推荐答案

i =材料(x)#Material是一个蟒蛇课

完成

你想要一本字典。


M = dict()

for x在xrange(1,4):

M [x] =材料(x)

You want a dictionary.

M = dict()
for x in xrange(1, 4):
M[x] = Material(x)
