lpad
lpad(string, n, p)
Make a string at least n columns wide when printed, by padding on the left with copies of p.
Examples
julia> lpad("Julia", 10, "*")
"*****Julia"
julia> lpad("25", 5, "0")
"00025"
julia> lpad("Hello, World!", 15, "-")
"Hello, World!"
julia> lpad("Julia", 3, "*")
"Julia"- The first example pads the string "Julia" with five asterisks on the left to make it at least 10 columns wide.
- The second example pads the string "25" with three zeroes on the left to make it at least 5 columns wide.
- The third example doesn't require any padding since the string "Hello, World!" is already wider than 15 columns.
- The fourth example doesn't perform any padding since the string "Julia" is already wider than 3 columns.
Common mistake example:
julia> lpad("Julia", -5, "*")
ERROR: DomainError with -5:
Padding width must be non-negativeIn this example, a negative padding width -5 is provided, which results in a DomainError. The padding width must be a non-negative value. Always ensure that the padding width is a valid input to avoid such errors.
