也可能出现逻辑上不正确的缩进,但不会导致出现错误消息。 One common form of this is attachingelse:to afororwhileloop rather than (as intended) the correspondingif:.如果您需要关闭 OP 所做的问题,请参阅Python while 语句中的 Else 子句。 崇高文本 3 如果碰巧你在 Sublime Text 3 中编码,这可以帮助...
Python语法要求在一份运行代码中的所有for，if/else的语句':'的下一行要统一缩进量（有’一个制表符（TAB键）‘，’两个空格‘，和’三个空格‘可以选择）如果缩进量不统一（比如TAB键和四个空格混用），则程序便会报错IndentationError: unindent does not match any outer indentation level（缩进不...
for i in range(1, 6): s = s + i print( s) # 这里的缩进和上一行不一致 如果不理解缩进,可以参考理解Python的代码缩进 - 知乎 (zhihu.com)。 2.NameError: name 'xxx' is not defined 某个变量没有定义就去使用它。 for i in range(1, 6): s = s + i # 变量s没有定义,在for语句之前...
Firstly in you script, you don't need the whole while loop. For f in fields will already iterate through the fields in the fields list. So you don't need i. And the whole of the while inner block should come in one indentation. for field in fields: statsFields = [[field,"COUNT"...
其他编程语言使用花括号表示代码块,而Python使用空格。这意味着Python期望代码中的空白具有可预测性。如果代码块中有一行空格数错误,则会引发IndentationError: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 1# indentation.py2deffoo():3foriinrange(10):4print(i)5...
(Update: As a few have pointed out, what you might need is justfor i in spam:rather than the above code. But the above is for the very legitimate case where you need the index in the body of the loop, rather than just the value itself.) ...
for i in X_df: X_ret[i] = X_df[i] * y_.values # print(i) X_ret = pd.DataFrame.from_dict(X_ret) 千万不要在loop里面改dataframe的内存(因为indexing很慢),用{dict},或者numpy array代替。 def calc_smma(src, length): length = int(length) ...
仔细检查了几遍代码,发现indent没有错误!之后试将所有indent都用空格代替,程序就跑起来了。具体原因可能是IDLE环境内的Tab键有小bug。
If the tab width is 8, which is standard for a lot of systems, then theprintstatement will look like it’s inside theforloop. The console will print'done'after each number. If the tab width is 3, then theprintstatement looks out of place. In this case, line 5 doesn’t match up ...
Python解释器可以执行的指令称为语句。例如， a=1是一个赋值语句。 if、 for、 while等其它语句我们后续再讨论。LATEX
