A boolean value can go directly into a conditional (if) statement if programRepeated: If programRepeated is equal to true, then the code block will execute. Some notes on your code though: = is an assignment operator. If you would like to check if something is equal, please use two equal signs ==. Your code will … Read more
Just you can use int(): number=int(input(‘Enter a number? ‘)) print(number) Otherwise, to be fool-proof, use try..except: while True: try: number=int(input(“Enter a number ? “)) break except ValueError: print(“Please input a vaild number !!”) solved How to convert a string to integer entered in input functon? [duplicate]
You are first assigning an empty list to x: x = [] And then you assign a single int (twice): for i in range (2): x = int(input(“enter a number: “)) 1: x = [] 2: x = first user input 3: x = second user input What you want to do is append the … Read more
If there is an if statement after an elif, this means this a different block of if statements. For example, if I do yes = “yes” no = “no” if yes == “yes”: print(“yee”) elif no == “no”: print(“:(“) It will only print “yee” as after it stopped after the first one worked. However, if … Read more

To fix the KeyError you can do the following thing: variable = {} for word in wordlist: variable[word] = [] for boolean in booleanlist: variable[word].append(True) Note that in this code snippet every keyword has the same list of Booleans, but that’s what you have given to us. edit: removed the global declaration, it was there … Read more
You need to check if titletext.a is None before you can use it for sure. for titles in title: titleheading = soup.findAll(‘h2’) for titletext in titleheading: if titletext.a: titlename = titletext.a titlelink =titlename.get(‘href’) print(i) print(titlelink) i+=1 2 solved Non Type object has no attribute get error
This operation is just doing the “merge” step of a Merge Sort and can be done in O(l1+l2) time. The general premise is to iterate over both (already sorted) lists at the same time, but only advance the list with the lowest head value, while using the advanced value in the resulting output. The operation … Read more
More than likely your code would read (in more “human” terms)if the length of original_term is more than zero characters print something. solved Python how to use the len() on pig game [closed]
The difference is that list1‘s value would be [‘abc’], while list2‘s value would be [‘a’, ‘b’, ‘c’]. Observe: >>> [‘a’ ‘b’ ‘c’] [‘abc’] >>> [‘a’, ‘b’, ‘c’] [‘a’, ‘b’, ‘c’] >>> This is due to the fact that adjacent string literals (delimited by whitespace), possibly using different quoting conventions, are allowed, and their meaning is … Read more
Most likely you are handling things as integers. You can use raw_input to read it in as is: response = raw_input(‘Enter your number –> ‘) And treat this as a string. print (“Your first digit is”, response[0]) solved I’m not sure of a way to go about this task using Python code [closed]

if Enter == “Yes” or “yes”: This is not how or works. This is interpreted as if (Enter == “Yes”) or “yes”:. In python, non-empty strings are always true, so all of the if statements like that will be true. I would suggest something like if Enter.lower() == “yes”: which takes care of all of … Read more
To quote the Python FAQ, raw string literals in Python were “designed to ease creating input for processors (chiefly regular expression engines) that want to do their own backslash escape processing”. Since the regex engine will strip the backslash in front of the quote character, Python doesn’t need to strip it. This behavior will most … Read more
