startwith方法是用来测试字符串是否以给定字符串开始。
in操作符用来检验一个给定字符串是否为另一个字符串的一部分。
find方法用来找出给定字符串在另一个字符串中的位置，或者返回-1以表示找不到子字符串。
str类也有以一个作为分隔符的字符串join序列的项目的整洁的方法，它返回一个生成的大字符串。
#!/usr/bin/python
# Filename: str_methods.py
name = ‘Swaroop‘ # This is a string object
if name.startswith(‘Swa‘):
print ‘Yes, the string starts with "Swa"‘
if ‘a‘ in name:
print ‘Yes, it contains the string "a"‘
if name.find(‘war‘) != -1:
print ‘Yes, it contains the string "war"‘
delimiter = ‘_*_‘
mylist = [‘Brazil‘, ‘Russia‘, ‘India‘, ‘China‘]
print delimiter.join(mylist)
$ python str_methods.py Yes, the string starts with "Swa" Yes, it contains the string "a" Yes, it contains the string "war" Brazil_*_Russia_*_India_*_China
