string = "pt.oldtoolbag.com"
capitalized_string = string.capitalize()
print('Old string: ', string)
print('Capitalized string:', capitalized_string)

When running the program, the output is:

Old string: pt.oldtoolbag.com
Capitalized string: pt.oldtoolbag.com

Example2: The first character is not a letter

string = "+　is an operator."
new_string = string.capitalize()
print('Original string:', string)
print('New string:', new_string)

When running the program, the output is:

Original string:　+　is an operator.
New string:　+　is an operator.
