Python stringis a sequence of characters. If within any of your programming applications, you need to go over the characters of a string individually, you can use the for loop here. Here’s how that would work out for you. word="anaconda"forletterinword:print(letter) Copy Output: a n ...
所以b是'banana'的第0个字母(“zero-eth”), a是第一个字母(“one-eth”),n是第二个字 母(“two-eth”)。 你可以使用一个包含变量名和运算符的表达式作为索引: >>> i = 1 >>> fruit[i] 'a' >>> fruit[i+1] 'n' 索引值必须使用整数。 否则你会得到: >>> letter = fruit[1.5] TypeError...
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 each word in a phrase. We can do that through an operation calledstring indexing.This...
Write a Python program to decapitalize the first letter of a given string. Use list slicing and str.lower() to decapitalize the first letter of the string. Use str.join() to combine the lowercase first letter with the rest of the characters. Omit the upper_rest parameter to keep the rest...
print(ord(one_letter)) Output: # Convert digit characters to their ASCII decimal numbers ascii_digits = string.digits # Output: 0123456789 for one_digit in ascii_digits[:5]: # Loop through 01234 print(ord(one_digit)) Output: 在上面的代码片段中,我们遍历字符串 ABCDE 和 01234,并将每个字符...

The % symbol marks the start of the specifier, while the s letter is the conversion type and tells the operator that you want to convert the input object into a string.If you want to insert more than one object into your target string, then you can use a tuple. Note that the number...

capitalize() It capitalizes the first letter of a string. center(width, fillchar) It returns a space-padded string with the original string centered to. count(str, beg= 0,end=len(string)) It counts how many times ‘str’ occurs in a string or in the substring of a string if the st...
for letter in 'Python': #这个语句的意思就是遍历'Python'这个字符串的每一个字符，赋值给letter，所以早for下面的语句块中letter每次都表示'Python'的一个字符，从头到尾
