Once the basic syntax of these data types is learnt, you can start growing your Python knowledge which will let you to more and more interesting operations with string handling. Always remember that the main goal of the learning process is towrite clean and efficient code to automate routinary ...
The split() method converts our string into a list, using the comma as the separator, and returns a list with three strings. Let’s try one more example: This time I specified a semicolon as the separator. Once again, we get a list of three separate strings. Since we have a list,...
print(" This is a sentence. ".split('s',1)) # [' Thi', ' is a sentence. '] 只根据第一个出现的s字符串拆分 字符串替换 Python的str类型还有一个方法,可以将给定字符串中的一个子字符串替换为另一个子字符串: str.replace(old, new[, count]): print('创帆云'.replace('帆','易')) 将...
