Separate Strings by Specific Separators¶

Python split & Rust split_whitespace¶

by Whitespace (no upper bound)¶

result : [“some”, “useful”, “data”]

# Python

# Setup

s = "    some useful data    "

# Get Result

result = s.split()

// Rust

// Setup

let s = "    some useful data    ";

// Get Result

// .split_whitespace() will return an iterator

let result : Vec<_> = s.split_whitespace().collect();
let result : Vec<&str> = s.split_whitespace().collect();

Notice: If you use .split(‘ ‘) in Rust, you will get a different result. Like this :

# Python

s.split(" ")    # ["", "", "", "", "some", "useful", "data", "", "", "", ""]

// Rust

let result : Vec<_> = s.split(' ').collect();       // ["", "", "", "", "some", "useful", "data", "", "", "", ""]
let result : Vec<&str> = s.split(' ').collect();    // ["", "", "", "", "some", "useful", "data", "", "", "", ""]

by Whitespace (with upper bound)¶

result : [“some”, “useful data “]

# Python

# Setup

s = "    some useful data    "

# Get Result

result = s.split(maxsplit=1)

// Rust

// Setup

let s = "    some useful data    ";

// Get Result

Python split & Rust split¶

by Any Character (no upper bound)¶

result : [“col1”, “col2”, “col3”, “col4”]

# Python

# Setup

s = "col1,col2,col3,col4"

# Get Result

result = s.split(',')

// Rust

// Setup

let s = "col1,col2,col3,col4";

// Get Result

let result: Vec<_> = s.split(',').collect();

by Any Character”s” (no upper bound)¶

result : [“col1”, “”, “col2”, “”, “col3”, “”, “col4”]

# Python

# Setup

s = "col1!?col2?!col3!?col4"

# Get Result

[TODO]

// Rust

// Setup

let s = "col1!?col2?!col3!?col4";

// Get Result

let result: Vec<_> = s.split(|c: char| "!?".contains(c)).collect();

by Any String (no upper bound)¶

result : [“col1”, “col2”, “col3”, “col4”]

# Python

# Setup

s = "col1::col2::col3::col4"

# Get Result

result = s.split("::")

// Rust

// Setup

let s = "col1::col2::col3::col4";

// Get Result

let result: Vec<_> = s.split("::").collect();

by Any String”s” (no upper bound)¶

result : [“col1”, “col2”, “col3”, “col4”]

# Python

# Setup

s = "col1//col2::col3%%col4"

# Get Result

[TODO]

// Rust

// Setup

let s = "col1//col2::col3%%col4";

// Get Result

[TODO]

by Complex Condition (no upper bound)¶

by Regular Expression (no upper bound)¶

Python split & Rust splitn¶

by Any Character (with upper bound)¶

result : [“col1”, “col2”, “col3,col4”]

# Python

# Setup

s = "col1,col2,col3,col4"

# Get Result

result = s.split(',', 2)    # maxsplit = 2, max length is 3

// Rust

// Setup

let s = "col1,col2,col3,col4";

// Get Result

let result: Vec<_> = s.splitn(3, ',').collect();    // count = 3, max length is 3

by Any Character”s” (with upper bound)¶

result : [“col1”, “”, “col2”, “”, “col3!?col4”]

# Python

# Setup

s = "col1!?col2?!col3!?col4"

# Get Result

[TODO]

// Rust

// Setup

// Get Result

let result: Vec<_> = s.splitn(5, |c: char| "!?".contains(c)).collect();         // count = 3, max length is 3
let result: Vec<_> = s.splitn(5, |c: char| str::contains("?!", c)).collect();

by Any String (with upper bound)¶

result : [“col1”, “col2”, “col3::col4”]

# Python

# Setup

s = "col1::col2::col3::col4"

# Get Result

result = s.split("::", 2)   # maxsplit = 2, max length is 3

// Rust

// Setup

let s = "col1::col2::col3::col4";

// Get Result

let result: Vec<_> = s.splitn(3, "::").collect();   // count = 3, max length is 3

Python rsplit & Rust rsplit¶

Python rsplit & Rust rsplitn¶

Python splitlines & Rust lines¶

result : [“We”, “Are”, “The”, “World”, “”, ”!!!”]

# Python

# Setup

s = "We\nAre\nThe\nWorld\n\n!!!"

# Get Result

result = s.splitlines()

// Rust

// Setup

let s = "We\nAre\nThe\nWorld\n\n!!!";

// Get Result

let result: Vec<_> = s.lines().collect();
