Understanding list comprehension

[Drone4four]

I’m taking Colt Steele’s Udemy course called “The Modern Python 3 Bootcamp”. I’m on Section 13 on List Comprehension.

The instructor uses this as an example:

name = 'Nebuchadnezzar'
print([char.upper() for char in name])

Here is the output:
['N', 'E', 'B', 'U', 'C', 'H', 'A', 'D', 'N', 'E', 'Z', 'Z', 'A', 'R']

In my pseudo code that I came up with, these two lines could be read as: "Give me the uppercase format of every character for every character inside the name variable (which is a string) containing: 'Nebuchadnezzar'."

Is that pseudo code correct?

I am now taking the above list comprehension explanation a step further by trying to do something the course instructor did not do, which is re-write the simple algorithm as a regular for loop. Here is my valiant attempt:

name = 'Nebuchadnezzar'
new_name = []
for char in name:
    new_name = char.upper()
    char + char  
print(new_name)

The output is just R. I was expecting: ['N', 'E', 'B', 'U', 'C', 'H', 'A', 'D', 'N', 'E', 'Z', 'Z', 'A', 'R']

I’m not sure why or what I am doing wrong. I tried adding the append method to line 5 but that threw a syntax error. Would someone here be able to rewrite the original list comprehension as a regular for loop?

Here are some of the resources I have already consulted:

• "How to create a list of random integers in python?"
  
• My old thread titled: "Creating list out of the first letter of every word in a string" (but @volcano63’s post specifically)
  
• "question about list comprehension"
  
• "List Comprehensions in Python"
  
• "Python List Comprehension"
  

By the way, more of my list-comprehension practice that I have done today can be found here in a Jupyter Notebook in my GitHub repo.
