語法錯誤：無法分配追加

Question

到函數調用我有下面的代碼，它似乎我使用append以錯誤的方式，因爲我越來越：SyntaxError: can't assign to function call

i = 0 
distance = []  
distance.append(i) = measureDistance.Distance2BetweenPoints(p1, p2) 

我怎樣才能解決這個問題？

謝謝。

Answer 1

如果你想在i位置插入的measureDistance.Distance2BetweenPoints(p1, p2)的結果，你應該做的 -

distance.insert(i, measureDistance.Distance2BetweenPoints(p1, p2)) 

如果要追加結果到最後，你應該改爲做 -

distance.append(measureDistance.Distance2BetweenPoints(p1, p2)) 

Answer 2

或者使用

i=0 
distance = []  
distance.insert(i,measureDistance.Distance2BetweenPoints(p1, p2) 

或使用

distance = []  
distance.append(measureDistance.Distance2BetweenPoints(p1, p2))
