print("Strings are not equal") 在这个例子中,由于str1和str2不相等,程序将输出“Strings are not equal”。 字符串长度 有时我们可能需要根据字符串的长度来做决策,我们可以使用len()函数来获取字符串的长度: s = "Python" if len(s) > 5: print("The string is long") else: print("The string is...

[ STRING1 > STRING2 ] 如果 “STRING1” sorts after “STRING2” lexicographically in the current locale则为真。 [ ARG1 OP ARG2 ] “OP” is one of -eq, -ne, -lt, -le, -gt or -ge. These arithmetic binary operators return true if “ARG1” is equal to, not equal to, less than...

Python语言采用严格的缩进来表示程序逻辑。也就是我们所说的Python程序间的包含与层次关系。一般代码不要求缩进,顶行编写且不留空白。在if、while、for、def、class等保留字所在完整语句后通过英文的“:”结尾并在之后行进行缩进,表明后续代码与紧邻无缩进语句的所属关系。
