# -*- coding: UTF-8 -*-

random_string = 'this is good    '

# Spaces at the end of the string will be removed
print(random_string.rstrip())

# 'si oo' are not trailing characters, so nothing is removed
print(random_string.rstrip('si oo'))

# In 'sid oo', 'd oo' are trailing characters, 'ood' is removed from the string
print(random_string.rstrip('sid oo'))

# 'm/' are trailing characters, no '.' trailing character was found, 'm/' is removed from the string
website = 'www.example.com/'
print(website.rstrip('m/.'))


# Remove commas (,), periods (.), and the letters s, q, or w; these are all trailing characters
txt = "banana,,,,,ssqqqww....."
x = txt.rstrip(",.qsw")
print(x)
# Remove trailing character *
str = "*****this is string example....wow!!!*****"
print (str.rstrip('*'))
print(x)
