In addition, we canaccess just a specific characteror aslice of charactersof a string. We might want to do this, for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of...
"char="l"count=text.count(char)print(f"The character '{char}' appears{count}times in the string.") 1. 2. 3. 4. 上述代码中,我们定义了一个字符串text,并使用count()函数统计了字符l在字符串中出现的次数。最后,使用print()函数打印了统计结果。 方法二:使用循环遍历字符串 除了使用内置函数count(...
In [55]: "{0:#>20}".format("string") #使用#号会有个小bug ...: Out[55]: '###string' In [60]: '{0:+<20}'.format("string") #向右对齐填充+ Out[60]: 'string+++++++++' In [61]: '{0:+^20}'.format("string") #剧中对齐填充+ Out[61]: '+++++string+++++' 精度...
这段代码的输出结果同样是The character a is not present in the string。 方法三:使用count()方法 Python中的字符串类还提供了一个count()方法,可以用于统计一个字符在字符串中出现的次数。可以通过以下方式使用: char='l'string='hello world'ifstring.count(char)>0:print(f'The character{char}is present...
