Python if len("string") <= 1: how to print the word? @codeacademy
提问by Adam Todorovic
print "Welcome to the English to Pig Latin translator!"
original = raw_input ("Type the word you want to translate!")
def Pytranslator():
if len("string") <= 1:
print original
else:
return "empty"
I want to print the word if it has more than one (1) letter. I've tried
如果单词有超过一 (1) 个字母，我想打印它。我试过了
return True print original

You are testing the length of the wrong thing. Test originalinstead:
你正在测试错误的东西的长度。original改为测试：
if len(original) <= 1:
print original
len("string")is alwaysgoing to be 6, the number of characters in the value "string":
len("string")是始终将是6，在价值的字符数"string"：
>>> len("string")
6
