Run your first Python

A single = is assignment, not a question about equality. The name on the left is given the value on the right, so minutes = 60 means that every later mention of minutes stands for 60. The equality test is ==, two characters, and mixing the two up is the mistake that trips up nearly everyone at first. Printing is a separate call, print, and joining text is done with + or an f-string, so the other options describe something else entirely.

Python is case sensitive, so name and Name are two different names. The line above created name with a lowercase n, and Name with a capital N was never created, so Python stops and says that name Name is not defined. Reading the last line of the traceback names the problem exactly. The + does work on strings, and print is happy to take the result, so neither of those is the cause here.

Python uses whitespace rather than braces to show which lines belong together. The four spaces before print are what tells Python that line is inside the loop; remove them and the line runs once, after the loop, which is a different program. Most other languages use braces for this job, and Python is stricter than you expect: mixing tabs and spaces, or an inconsistent indent, is an error rather than a warning.

A slice is written start:stop:step. Leaving start and stop out means the whole string, and a step of minus one means walk it backwards, so word[::-1] reverses the word and Termux becomes xumreT. A step of one, which is the default, would give the string unchanged. Omitting start and stop is allowed, so this does not raise an error, and that is what makes the idiom so short.
