  • If you print some string `s` without a newline character at the end, instead of
  • ```
  • print(s,end="")
  • ```
  • write
  • ```
  • print(end=s)
  • ```
  • to save two bytes.
  • Note that this only works for strings, not for other types.
  • Note also that if you print more than one string, then the `end=` part will also prevent inserting spaces between them; to avoid getting those extra spaces, in that case you'll need to use string concatenation (string addition) instead.
  • For example, instead of
  • ```
  • print(s,t,end="")
  • ```
  • use
  • ```
  • print(end=s+t);
  • ```
  • Again, this only works if all arguments are strings.
  • If you print some string `s` without a newline character at the end, instead of
  • ```
  • print(s,end="")
  • ```
  • write
  • ```
  • print(end=s)
  • ```
  • to save two bytes.
  • Note that this only works for strings, not for other types.

If you print some string `s` without a newline character at the end, instead of
```
print(s,end="")

write
```
print(end=s)
```
to save two bytes.

Note that this only works for strings, not for other types.

Note also that if you print more than one string, then the `end=` part will also prevent inserting spaces between them; to avoid getting those extra spaces, in that case you'll need to use string concatenation (string addition) instead.

For example, instead of
```
print(s,t,end="")

print(end=s+t);
