Hello friends, in this article you will learn how to shift numbers in Python in a string from any place of string to the start of the string. For example, making bnj67jbn to 67bnjjbn, simply we need to remove integers from inside of a string and place them to start of the string. To check whether a character is a digit or not, we can use isdigit() method of Python.
Code to shift numbers in Python:
mystr='bnj67jbn'
mylist1=[]
mylist2=[]
for i in range(len(mystr)):
if mystr[i].isdigit():
mylist1.append(mystr[i])
else:
mylist2.append(mystr[i])
print(''.join(mylist1)+''.join(mylist2))Output:
Explanation:
So, we created a string, declared two empty lists, then inside for loop, we checked each character of string whether it is digit or not. If its a digit, we will append it to list 1 else list 2. At last, we are printing both lists by converting them to strings(using join() method) and joining them with + operator.
