I am writing my cover letter and currently I am writing "I am also a quick learner; I was able to learn Python in two days." But it doesn't seem to be very smooth. How can this phrase be better?
Perhaps separate your points by simply saying, "I am also a quick learner. For example, I was able to learn Python in two days."
Also since you're writing a resumé cover letter, you might want to qualify that you learned "the basics of Python" in two days rather than "everything there is to know about Python" which is what your statement seems to imply. Just a suggestion. Hope it helps.
