To convert an integer to a string, use the str() built-in function.

str(12345)

"{:02d}".format(5) 
=> output : "05"
//for Python 3.6+
print(f"{55:02d}")

str(2021)[-2:]
=> result: 21 
year = '2021'
year[-3:]
=> result: 021

By default, split() takes whitespace as the delimiter.

s = "a b c"
list = s.split()
#output: ['a', 'b', 'c']

Split by first 1 whitespace only.

s = "a b c"
list = s.split(' ', 1)
#output: ['a', 'b c']

lower() method converts all characters in a string into lowercase characters and returns it.

'Aa Bb'.lower() #outout: 'aa bb'

upper() method converts all characters in a string into uppercase characters and returns it.

'Upper case'.upper() #output: 'UPPER CASE'

swapcase() method converts all uppercase characters to lowercase of the given string, and vice versa.

'UPPER lower'.swapcase() #output: 'upper LOWER'

strip() removes both the leading and the trailing characters. lstrip() removes leading ones, rstrip() removes the trailing ones.

'  Hello   '.strip() #output: 'Hello'

b character appears in front of a string when you work with encoding and decoding. So to remove it , just decode the bytes.

bytesVariable.decode("utf-8")
