字符串 (str): 如“Hello”, ‘Python’ 布尔值 (bool): True, False 3 运算 +– / * % a = 10 b = 3 print(a + b) # 输出 13 print(a % b) # 输出 1 4if-elif-else if是条件判断语句,用于执行某些代码块。 elif(”else if” 的缩写)用来检查其他可能的条件,避免多个独立的if。 else...
The Python SyntaxError: invalid syntax is often caused when we use a single equals sign instead of double equals in an if statement.
这是明显的格式错误,楼主刚学python吧。 和C/C++不同,python对于代码块的区分是使用缩进进行区分的(C/C++是使用大括号) 这段代码这样改就行了#...for token in sent1: if token.islower(): print token, 'is a lowercase word' elif token.istitle(): print token, 'is a title word'#...00...
