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...
So Python returns a new string to me. 我也可以使用负索引进行切片。 I can also do slicing using negative indices. 例如,如果我键入S,减去3,Python将给出该序列中的最后三个字符,即h、o和n。 So for example, if I type S, minus 3, Python will give me the last three characters in that sequ...
Replace the last N characters in a String in Python The slice my_str[:-1] starts at index 0 and goes up to, but not including the last character of the string. main.py my_str = 'bobbyhadz.com' print(my_str[:-1]) # 👉️ bobbyhadz.co The syntax for string slicing is my...
If you want to include either type of quote character within the string, then you can delimit the string with the other type. In other words, if a string is to contain a single quote, delimit it with double quotes and vice versa:
>>> symbols[-1] # Last character ? >>> symbols[-2] # Negative indices are from end of string ? >>> 在Python 语言中,字符串是只读的。尝试通过将 symbols 字符串的第一个字符变为小写字母 ‘a’ 来验证这一点。>>> symbols[0] = 'a' Traceback (most recent call last): File "<stdin>...
The left edge of the first character in the string is numbered 0. We can slice from this location with the index i. The right edge of the last character of a string of n characters has the index n. We can slice from this location with the index j. For example:Python Copy ...

If you leave out the start index, the range will be started from the first character. a = “Intellipaat” print (a[2:]) The output will be: tellipaat Python Reverse String There isn’t any built-in function to reverse a given String in Python but the easiest way is to do that ...
