正如您在下面看到的，我输入了我的代码，前两个块工作正常。但是，当我进行插值时，我开始遇到问题。显示的最大错误在最后，即：TypeError：'float'类型的对象没有len（）
我还在学习这门语言，所以如果我的评论不好，请放轻松。
这是我的代码：
# Imported array of data from a text file.
q1, a1 = loadtxt("values.txt", unpack = True, skiprows = 1)
print q1
print a1
# Creating a while loop for this part of the code.
a = 3
b = -2
c = -9
q = 0.5
qt = 0.1
while q < 1.5:
print q, a
q += qt
a = a + b*qt
b = b + c*qt
# Interpolation
from scipy.interpolate import interp1d
f = interp1d(q,a,'cubic')
q1 = linspace(0.5,1.4,25)
a1 = f(q1)
plot(q1,a1, '-', q,a, 'o')
show()
