[英]if statement error: invalid syntax and expected an indented block
When executing my code below I get a syntax error: 在下面执行我的代码时,出现语法错误:
expected an indented block
预期缩进的块
I have checked the tabs are not spaces as suggested on other threads. 我检查了选项卡是否没有其他线程上建议的空格。 What is causing this?
是什么原因造成的?
if wallDirection = '-X':
xAxis = -buildingSectionWidth
First see What is the difference between an expression and a statement in Python? 首先看看Python中的表达式和语句有什么区别? An
if
statement requires an expression as its condition. if
语句需要使用表达式作为其条件。
wallDirection = '-X'
is a statement that assigns wallDirection
to the value -X
. wallDirection = '-X'
是将wallDirection
分配给值-X
的语句。 The expression you likely want here is wallDirection == '-X'
. 您在此处可能想要的表达式是
wallDirection == '-X'
。 The operator that tests for equality is ==
, not =
. 测试相等性的运算符是
==
,而不是=
。
if wallDirection == '-X':
xAxis = -buildingSectionWidth
