The method to find the specified string in python is as follows:

code

#查询
def selStr():
  sStr1 = 'jsjtt.com'
  sStr2 = 'com'
  #index查询某个字符串,返回索引
  nPos = sStr1.index(sStr2)
  if(nPos >=0):
    print 'sStr1中包括sStr2中的字符'
  print nPos
   
  #find 方法如果没有查询到返回-1
  nPos2 = sStr1.find('abc')
  print nPos2
  #查询到返回字符所在位置
  print sStr1.find('com')
   
selStr();
Copy after login

python splits the string

def split():
  sStr1 = 'ab,cde,fgh,ijk'
  sStr2 = ','
  #用find查找逗号所在的索引位置
  sStr1 = sStr1[sStr1.find(sStr2) + 1:]
  print sStr1
  #使用split函数分割字符串
  s = 'ab,cde,fgh,ijk'
  result = s.split(',')
  print(result)
  print(result[0])
split();
Copy after login
