Question

当我运行下面的脚本时，它会显示出来
SyntaxError：语法无效

single = True    

if single = True:
 print "Hey Girl, can I get your number ? "
else
 print "Bye. !"

Answer 1

简单地输入if single：which检查single是否为True并继续执行。如果single为False，它将移动到else语句。另外，你忘了把：放在else语句前面。

single = True

if single:
    print ("Hey Girl, can I get your number ? ")
else:
    print ("Bye. !")

Answer 2

你需要以确保else分支前面有冒号！请记住，Python非常注重空间，因此Python需要保持整洁，以便您喜欢。

single = True    

#Instead of just doing single-space indenting it would behoove you to use regular tabs
if single == True: #<- Also, also, instead of doing just one equal sign (which is assignment) You should use the equality operator '=='
    print "Hey Girl, can I get your number ? "
else: #<- You were missing a colon here
    print "Bye. !"
