In Julia, you can access the name and value of a symbol using the symbol_name and symbol_value functions respectively. Let’s see how we can achieve this.
Option 1: Using the symbol_name and symbol_value functions
# Define a symbol
symbol = :my_symbol
# Access the name of the symbol
name = symbol_name(symbol)
println("Name: ", name)
# Access the value of the symbol
value = symbol_value(symbol)
println("Value: ", value)
In this option, we define a symbol :my_symbol and then use the symbol_name function to access its name and the symbol_value function to access its value. The output will be:
Name: my_symbol
Value: my_symbol
Option 2: Using the string function
# Define a symbol
symbol = :my_symbol
# Access the name of the symbol
name = string(symbol)
println("Name: ", name)
# Access the value of the symbol
value = eval(symbol)
println("Value: ", value)
In this option, we define a symbol :my_symbol and then use the string function to access its name and the eval function to access its value. The output will be the same as in option 1:
Name: my_symbol
Value: my_symbol
Option 3: Using the @show macro
# Define a symbol
symbol = :my_symbol
# Access the name and value of the symbol using @show
@show symbol
# Access the value of the symbol
value = eval(symbol)
println("Value: ", value)
In this option, we define a symbol :my_symbol and then use the @show macro to access both its name and value. The output will be:
symbol = my_symbol
Value: my_symbol
Among the three options, the best one depends on the specific use case. Option 1 and 2 provide direct access to the name and value of the symbol, while option 3 offers a more convenient way to display the name and value during debugging or exploration. Choose the option that suits your needs best.
