Python | Convert String list to ascii values
• Last Updated : 29 Nov, 2019

Sometimes, while working with Python, we can have a problem in which we need to convert String List to ascii values. This kind of problem can occur many times. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using loop + `ord()`
This problem can be solved using above functionalities. In this, we iterate the list and convert each character to it’s ascii number using `ord()`.

 `# Python3 code to demonstrate working of``# Convert String list to ascii values``# using loop + ord()`` ` `# initialize list ``test_list ``=` `[``'gfg'``, ``'is'``, ``'best'``]`` ` `# printing original list ``print``(``"The original list : "` `+` `str``(test_list))`` ` `# Convert String list to ascii values``# using loop + ord()``res ``=` `[]``for` `ele ``in` `test_list:``    ``res.extend(``ord``(num) ``for` `num ``in` `ele)`` ` `# printing result``print``(``"The ascii list is : "` `+` `str``(res))`
Output :
```The original list : ['gfg', 'is', 'best']
The ascii list is : [103, 102, 103, 105, 115, 98, 101, 115, 116]
```

Method #2 : Using list comprehension +` ord()`
This is yet another way to perform this task. This is just shorthand to above problem in which we compact the code using list comprehension using similar logic.

 `# Python3 code to demonstrate working of``# Convert String list to ascii values``# using list comprehension + ord()`` ` `# initialize list ``test_list ``=` `[``'gfg'``, ``'is'``, ``'best'``]`` ` `# printing original list ``print``(``"The original list : "` `+` `str``(test_list))`` ` `# Convert String list to ascii values``# using list comprehension + ord()``res ``=` `[``ord``(ele) ``for` `sub ``in` `test_list ``for` `ele ``in` `sub]`` ` `# printing result``print``(``"The ascii list is : "` `+` `str``(res))`
Output :
```The original list : ['gfg', 'is', 'best']
The ascii list is : [103, 102, 103, 105, 115, 98, 101, 115, 116]
```
