This split() function returns a list where the string has been split at each match import re It is because search() function returns only a first match. Here we got only mobile number but not telephone number. Returns a match object if there is any match in the string import re It returns a list containing all the matches import re Some of the function that assist us to search a string in text are as follows: 1) Findall() Pattern is so created that it will look for pattern starting with “+” followed by three decimal number followed by space and ten decimal numbers. Here, d represents the decimal number(0-9). We’ve created a search pattern using compile function of re module. Just few lines of code and result is same. Now, let’s see how phone number verification can be done with regular expression: import re Then finally it checks all the remaining characters are decimal or not, if not it returns False. Then it checks there is space or not, if not it returns False. Then, it checks first three characters after “+” are decimal or not, if not it returns False. Then it checks the text begins with “+” or not, if not it returns False. Explanation of steps of verificationįirst of all, code checks whether the length of supplied text(mobile number for verification in string) is of length 15 or not, if not it returns False. We assume that the country code and 10 digit phone number is separated by space. And then phone number has 10 digits in it. As we know country code for Nepal is +977. We’ve taken mobile number of Nepal for verification. If this task is to be done manually without regular expression can be done in this way: def isValidNumber(text):
