String is the most commonly used data type in Python. We can use quotes (' or ") to create strings.
Creating a string is as simple as assigning a value to a variable.
For example: var1 = 'Hello World!'
Code example:
str = ‘0123456789’ print str[0:3] #截取第一位到第三位的字符 print str[:] #截取字符串的全部字符 print str[6:] #截取第七个字符到结尾 print str[:-3] #截取从头开始到倒数第三个字符之前 print str[2] #截取第三个字符 print str[-1] #截取倒数第一个字符 print str[::-1] #创造一个与原字符串顺序相反的字符串 print str[-3:-1] #截取倒数第三位与倒数第一位之前的字符 print str[-3:] #截取倒数第三位到结尾 print str[:-5:-3] #逆序截取
Result:
012 0123456789 6789 0123456 2 9 9876543210 78 789 96
