我正在使用Python的Flask將3D圖形的X，Y，Z值賦給Javascript（Plotly庫）。數據是這樣的： z = [1,1,1,1,1,1,1,1,1,1,1,1];
x = [0.0100,0.0420,0.0500,0.0508,0.0769,0.0883,0.0900,0.1101,0.1256,0.1300,0.1385,0.1607];
y = [0.0131,0.019
串聯可變我有3個variable print(obj.col1_expense.text) #test1
print(obj.col2_expense.text) #test2
print(obj.col3_expense.text) #test3
如何打印它的動態？ 我現在想這樣 for x in range(1, 4):
print("obj.col"+str(x)+"_e
我一直在試圖做一個函數，可以採取兩個任何大小的列表（比如說，列表A和列表B），並看到列表B是否出現在列表中A，但是連續且以相同的順序。如果以上情況屬實，則返回True，否則返回False。 例如， A:[9,0,**1,2,3,4,5,6,**7,8] and B:[1,2,3,4,5,6] is successful
A:[1,2,0,3,4,0,5,6,0] and B:[1,2,3,4,
在字符串中，我想使用re模塊查找長度大於4的所有單詞。 樣品輸入：This is good Python forum and its helping a lot to beginners. 輸出：['Python','helping','beginners] 下面我試過，但它不工作： match=re.findall(r'([\w]{4}).*',str1)
