Quick reference #

Some common string methods.

Method	Description	Example Input	Example Output
`str()`	Convert to string	`str(1)`	`"1"`
`len()`	Count the number of characters in a string	`len("Bob")`	`3`
`.lower()`	Lowercase everything	`"BOB".lower()`	`bob`
`.upper()`	Uppercase everything	`"bob".upper()`	`BOB`
`.count()`	Count the presence of a string in another string	`"hello hello".count("hello")`	`2`
`.find()`	Find first index for where some character or string appears. If the thing being sought isn’t present, return `-1`.	`"Why hello there".find("hello")`	`4`
`<string>.replace(<what to replace>, <replacement>)`	Replace stuff	`"Why hello there".replace("there", "you")`	`'Why hello you'`
`<string>.zfill(<number of desired digits>)`	Pad with zeros	`str(50).zfill(5)`	`'00050'`

<string> + " " + <another string>

Or use formatting (formatted string).

message = '{} , {}'.format(<string1>, <string2>)

Or with fstring, where variables can be inserted directly between curly braces.

f'{<string1>}, {<string2>}.'

Can modify in place with fstring. For example:

f'{<string1>}, {<string2>.upper()}.'
