在这段代码中,我们使用了Python中的in运算符来判断字符串input_string中是否包含目标字符target_char,如果包含则将contains_char设为True,否则设为False。 步骤3:输出判断结果 # 输出判断结果ifcontains_char:print(f"The string '{input_string}' contains the character '{target_char}'.")else:print(f"The st...
string = "Hello World" char = "a" if char in string: print(f"The character '{char}' is found in the string.") else: print(f"The character '{char}' is not found in the string.") 输出结果将是:The character 'a' is not found in the string.,因为字符a并不存在于字符串中。 问题...

由于Python没有单独的character类型,索引字符串会产生长度为1的字符串。也就是说,对于非空字符串s,s [0] == s [0:1]。 Python也没有可变的字符串类型,但str.join()或io .StringIO可用于从多个片段高效地构建字符串。 版本3.3中更改:为了向后兼容Python 2系列,字符串文字再次允许使用u前缀。它对字符串文字...
Check: --> String contains character: print result Check: --> String does not contain character: print result 在上面的状态图中,我们展示了check_character函数的执行流程。当字符串包含指定字符时,输出String contains character;当字符串不包含指定字符时,输出String does not contain character。
