sequence

A sequence in Nim is similar to Python's list. It's a dynamic array.

import strformat
import strutils

var
names = @["Alice", "Bob", "Cecile"]

for name in names:
echo name

echo names.len()

for idx, name in names:
echo &"{idx}) {name}"

names.add("Daniel")
echo names

echo "Bob" in names

echo names.join(" -> ")

Output:

Alice
Bob
Cecile

3

0) Alice
1) Bob
2) Cecile

@["Alice", "Bob", "Cecile", "Daniel"]

true

Alice -> Bob -> Cecile -> Daniel

Create an empty sequence

import strutils

var
nums = newSeq[int]()

echo nums

nums.add(12)
nums.add(4)

echo nums

echo nums.join("; ") # the elems will be converted to strings automatically

Output:

@[]

@[12, 4]

12; 4
