Description The method index() returns the lowest index in list that obj appears. Syntax Following is the syntax for index() method − list.index(obj) Parameters obj − This is the object to be find out. Return Value This method returns index of the found object otherwise raise an exception indicating that value does not find. Example: Python 3.6.6 (v3.6.6:4cf1f54eb7, Jun 27 2018, 03:37:03) [MSC v.1900 64 bit (AMD64)] on win32 Type "copyright", "credits" or "license()" for more information. >>> testList = ['abc','foo','bar','woo','adc'] >>> print("Index of 'foo' is:%d"%testList.index('foo')) Index of 'foo' is:1 >>> print("Index for 'bar' is:%d"%testList.index('bar')) Index for 'bar' is:2 >>>

Description It determines if string str occurs in string, or in a substring of string if starting index beg and ending index end are given. Syntax str.find(str, beg=0, end=len(string)) Parameters str − This specifies the string to be searched. beg − This is the starting index, by default its 0. end − This is the ending index, by default its equal to the length of the string. Return Value Index if found and -1 otherwise. Example: Python 3.6.6 (v3.6.6:4cf1f54eb7, Jun 27 2018, 03:37:03) [MSC v.1900 64 bit (AMD64)] on win32 Type "copyright", "credits" or "license()" for more information. >>> str1 = "This is a string to test the find method." >>> str2 = "string" >>> print(str1.find(str2)) 10 >>> print(str1.find(str2,10)) 10 >>> print(str1.find(str2,10+1)) -1 >>>
