strip() Python String strip() function will remove leading and trailing whitespaces. If you want to remove only leading or trailing spaces, use lstrip() or rstrip() function instead.
String result = str. trim(); The trim() method will remove both leading and trailing whitespace from a string and return the result.
The Python String strip() method is part of the built-in function available in python. The function will remove given characters from the start and end of the original string. This function is very helpful in removing the whitespaces at the start and end of the given string, as shown in the example.
use printf(" %d",a[i][j]). Simply put space before rather than after. You can use \b for backspace as well.
>>> " xyz ".rstrip()
' xyz'
There is more about rstrip in the documentation.
You can use strip() or split() to control the spaces values as the following, and here is some test functions:
words = " test words "
# Remove end spaces
def remove_end_spaces(string):
return "".join(string.rstrip())
# Remove first and end spaces
def remove_first_end_spaces(string):
return "".join(string.rstrip().lstrip())
# Remove all spaces
def remove_all_spaces(string):
return "".join(string.split())
# Remove all extra spaces
def remove_all_extra_spaces(string):
return " ".join(string.split())
# Show results
print(f'"{words}"')
print(f'"{remove_end_spaces(words)}"')
print(f'"{remove_first_end_spaces(words)}"')
print(f'"{remove_all_spaces(words)}"')
print(f'"{remove_all_extra_spaces(words)}"')
output:
" test words "
" test words"
"test words"
"testwords"
"test words"
