可以对 String/List 进行乘法运算,这个方法,可以使用它们任意倍增。 n = 3 # number of repetitions my_string = "abcd" my_list = [1,2,3] print(my_string*n) # abcdabcdabcd print(my_string*n) # [1,2,3,1,2,3,1,2,3] 1. 2. 3. 4. 5. 6. 7. 8. 9. 有一个很有意思的用法,...
So, for strings, the length is the number of characters in the string. For example: This is a string!!← This string has a length of 18, including the letters, spaces, and exclamation marks. String Indexes Finding a String Within a String Replacing a Substring Slicing a String Lesson ...
Substring in Python language is a sequence of characters with one more string. It is also termed as ‘Slicing of String’. Python’s array functionality known as ‘slicing’ can be applied to our strings.
Use negative indexes to start the slice from the end of the string: Example Get the characters: From: "o" in "World!" (position -5) To, but not included: "d" in "World!" (position -2): b = "Hello, World!" print(b[-5:-2]) Try it Yourself » Exercise...
