To find the type of a variable/value, we use the typeof() function – it accepts a parameter whose type to be found and returns its data type.

为了找到变量/值的类型，我们使用typeof()函数-它接受要查找其类型的参数并返回其数据类型。

Example 1:

范例1：

name = "Mark"age = 21# printing the type of the valuesprintln("typeof(\"Mark\"): ", typeof("Mark"))println("typeof(21): ", typeof(21))# printing the type of the variablesprintln("typeof(name): ", typeof(name))println("typeof(age): ", typeof(age))

Output

输出量

typeof("Mark"): Stringtypeof(21): Int64typeof(name): Stringtypeof(age): Int64

Example 2:

范例2：

# variablesa = 10b = 10.23c = 'c'd = "Hello"e = truef = falseg = 0h = 0.0# printing the type of the variablesprintln("typeof(a): ", typeof(a))println("typeof(b): ", typeof(b))println("typeof(c): ", typeof(c))println("typeof(d): ", typeof(d))println("typeof(e): ", typeof(e))println("typeof(f): ", typeof(f))println("typeof(g): ", typeof(g))

Output

输出量

typeof(a): Int64typeof(b): Float64typeof(c): Chartypeof(d): Stringtypeof(e): Booltypeof(f): Booltypeof(g): Int64
