Python string manipulation (string substitution, delete, intercept, copy, join, compare, find, include, Case transform, split, etc.)

Go to spaces and special symbols

S.strip (). Lstrip (). Rstrip (',')

Copy string

# strcpy (SSTR1,SSTR2) ' strcpy '  ='strcpy2'print sStr2

Connection string

# strcat (SSTR1,SSTR2) ' strcat '  'append'+ = sStr2print sStr1

Find characters

# STRCHR (SSTR1,SSTR2) # < 0 for not found ' STRCHR '  's'= sstr1.index (sStr2)print NPos

Comparing strings

# strcmp (SSTR1,SSTR2) ' STRCHR '  'strch'print cmp (SSTR1,SSTR2)

Scans whether a string contains the specified character

# strspn (SSTR1,SSTR2) ' 12345678 '  '456'#sStr1 and chars both in SStr1 and sStr2print  and SSTR2)

String length

# strlen (SSTR1) ' strlen ' print len (SSTR1)

Converts the case in a string

# strlwr (SSTR1) ' jcstrlwr '  = sstr1.upper ()#sStr1 = Sstr1.lower ()print sStr1

Appends a string of the specified length

# strncat (sstr1,sstr2,n) ' 12345 '  'abcdef'= 3+ = sstr2[0:n]print sStr1

String specifying length Comparison

# strncmp (sstr1,sstr2,n) ' 12345 '  '123bc'= 3print cmp (Sstr1[0:n],sstr2[0:n])

Copy characters of specified length

# strncpy (sstr1,sstr2,n) "'  '12345'= 3= sstr2[0:n]print sStr1

Replaces the first n characters of a string with the specified character

# Strnset (sstr1,ch,n) ' 12345 '  'r'= 3= n * ch + sstr1[3:]print sStr1

Scan string

# strpbrk (SSTR1,SSTR2) ' Cekjgdklab '  'gka'     =-1 for in SSTR1: if   in sStr2:        = Sstr1.index (c)        breakprint NPos

Flip string

# Strrev (SSTR1) ' ABCDEFG '  = sstr1[::-1]print sStr1

Find string

# strstr (SSTR1,SSTR2) ' ABCDEFG '  'cde'print sstr1.find (SSTR2)

Split string

# strtok (SSTR1,SSTR2) ' Ab,cde,fgh,ijk '  ','= Sstr1[sstr1.find (SSTR2) + 1:]print  SSTR1# or 'ab,cde,fgh,ijk'print(S.split ( ' , '))

Connection string

' , '  = ['Brazil'Russia'India ' '  China ' ]print delimiter.join (mylist)

Implementation of Addslashes in PHP

defAddslashes (s): D= {'"':'\\"',"'":"\ \ '"," /":"\\\0","\\":"\\\\"}    return "'. Join (D.get (c, c) forCinchs) s="John ' Johny ' Doe (a.k.a. \ "Super joe\") \\\0"PrintsPrintAddslashes (s)

Show only letters and numbers

defOnlycharnum (s,oth="'): S2=S.lower (); Fomart='abcdefghijklmnopqrstuvwxyz0123456789'     forCinchS2:if  notCinchfomart:s= S.replace (c,"'); returns;Print(Onlystr ("a000 aa-b"))

Intercept string

str = ' 0123456789 -PrintStr[0:3]#Intercept first-to-third-digit charactersPrintstr[:]#truncate all characters of a stringPrintStr[6:]#Intercept the seventh character to the end of thePrintSTR[:-3]#intercept from the beginning to the third of the last characterPrintSTR[2]#interception of the third characterPrintSTR[-1]#Intercept the first character of the countdownPrintSTR[::-1]#create a string opposite to the original string orderPrintSTR[-3:-1]#intercept the characters before the third and last digitPrintStr[-3:]#intercept the third to the end of the countdownPrintSTR[:-5:-3]#What do you mean, you don't understand?
