我试图在python中绘制一个函数,但每次我去测试它时,它只是说:
" plt.plot(T,V)
^
SyntaxError,语法无效"
from __future__ import division
import numpy as np
import matplotlib.pyplot as plt
import math
def someFunction(filename, posx, posy, posz):
//generic code
//to test
//limits...
data = np.genfromtxt(filename,delimiter=",")
i = 0
V = 0
while i < len(data):
q = data[i,0]
x = data[i,1]
y = data[i,2]
z = data[i,3]
r = <some computation>
V += <some computation>
i += 1
return V
def plotFunction(filename):
V = []
t = []
for i in np.arange(0,20,0.1):
t.append(i)
V.append(someFunction(filename,i,i**2+2,i-3)
plt.plot(t,V)
plt.savefig('plot.pdf')
任何帮助都会非常感激。
答案 0 :(得分:1)
V.append(someFunction(filename,i,i**2+2,i-3))
缺少最后一个结束括号
