示例 #1：

# Ruby code for zip() method
  
# declaring array
a = [18, 22, 33, nil, 5, 6]
  
# declaring array
b = [1, 4, 1, 1, 88, 9]
  
# declaring array
c = [18, 22, 50, 6]
  
  
# zip method example
puts "zip() method form : #{a.zip(b)}\n\n"
  
puts "zip() method form : #{b.zip(c)}\n\n"
  
puts "zip() method form : #{c.zip(c)}\n\n"

输出 ：

zip() method form : [[18, 1], [22, 4], [33, 1], [nil, 1], [5, 88], [6, 9]]

zip() method form : [[1, 18], [4, 22], [1, 50], [1, 6], [88, nil], [9, nil]]

zip() method form : [[18, 18], [22, 22], [50, 50], [6, 6]]

示例 #2：

# Ruby code for zip() method
  
# declaring array
a = ["abc", "nil", "dog"]
  
# declaring array
c = ["cat", nil]
  
# declaring array
b = ["cow", nil, "dog"]
  
  
# zip method example
puts "zip() method form : #{a.zip(b)}\n\n"
  
puts "zip() method form : #{b.zip(c)}\n\n"
  
puts "zip() method form : #{c.zip(c)}\n\n"

输出 ：

zip() method form : [["abc", "cow"], ["nil", nil], ["dog", "dog"]]

zip() method form : [["cow", "cat"], [nil, nil], ["dog", nil]]

zip() method form : [["cat", "cat"], [nil, nil]]
