What if we want to have more than three possibilities, though? We can do this by writing more than oneelifstatement into our code. In thegrade.pyprogram, let’s rewrite the code so that there are a few letter grades corresponding to ranges of numerical grades: ...
Thelen()function can be used to verify that \n is treated as a single character. An escape sequence is not like a regular character—it needs to be interpreted differently. When we escape the letter ‘n’ by putting a backslash in front it becomes the newline character. ...
Now, let’s go ahead and see how can we have a sequence of numbers in each row with python: depth = 6 for number in range(1, depth): for i in range(1, number + 1): print(i, end=' ') print("") Code Explanation: We start off by initializing the value of depth to be 6....
