If I understand the correct output format word-O, you can try something like this: words = open(‘filename’).read().split() labeled_words = [word+”-O” for word in words] # And now user your output format, each word a line, separate by tabs, whatever. # For example new lines with open(‘outputfile’,’w’) as output: output.write(“\n”.join(labeled_words)) 3 solved How to add a … Read more
raw_input returns a string. Strings are never equal to numbers. >>> ‘0’ == 0 False Compare the string with a string. For example, to check whether the string starts with specific character (sub-string), using str.startswith: if number.startswith(‘0’): … solved Determining the First Digit
Your function never actually makes the calculation. I think you’re looking for something like this: def Cel2Fah(temp): fah = temp * 9.0/5.0 + 32 return fah You can calculate 28C in Fahrenheit by calling the function like this: Cel2Fah(28) If you want to print 29C in Fahrenheit with 2 decimal places, here is ALL the … Read more
You can use the partition method for this. It’s part of the built-in str type. >>> help(str.partition) partition(self, sep, /) Partition the string into three parts using the given separator. This will search for the separator in the string. If the separator is found, returns a 3-tuple containing the part before the separator, the separator … Read more
In python 2.7 you can use random.choice (singular) and have it executed on a range: x = ”.join(random.choice(‘123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz’) for _ in range(4)) 5 solved Base58 Random String generator
No, there is no faster way of processing a file line by line, not from Python. Your bottleneck is your hardware, not how you read the file. Python is already doing everything it can (using a buffer to read the file in larger chunks before splitting into newlines). I suggest upgrading your disk to an … Read more
the way your code is structured, you iterate over the matches in your for loop, then, when the loop is finished, you save the last match in your CSV. You probably want to write each match in your CSV instead, inside the for loop. try to replace the last lines of your code (starting at … Read more
You can use a regex to look for words that follow the word python, for example >>> import re >>> re.findall(r’Python (\w+)’, s) [‘is’, ‘has’, ‘features’, ‘interpreters’, ‘code’, ‘is’, ‘Software’] Since this list may contain duplicates, you could create a set if you want a collection of unique words >>> set(re.findall(r’Python (\w+)’, s)) {‘Software’, ‘is’, … Read more
This also works: pairs = dict([tuple(namn[i:i+2]) for i in range(0, len(namn), 2)]) for name, age in sorted(pairs.items()): print(“%s: %d” % (name, age)) avg_age = sum(pairs.values())/ len(pairs) print(“Average Age: %f” % (avg_age)) Output: Anna: 27 Emelie: 32 Erik: 30 Johanna: 29 Jonas: 26 Josefine: 20 Kalle: 23 Lena: 22 Peter: 19 Average Age: 25.333333 You could … Read more

You can do it by: a =[ [0,1,0,0,0,1], [4,1,0,3,2,0], [0,0,1,0,0,0], [0,1,0,0,1,0], [0,0,0,0,1,0], [0,0,0,0,0,0], ] b = [0, 1, 3] c = [[a[i][j] for j in b] for i in b] print(c) # ===> # [[0, 1, 0], [4, 1, 3], [0, 1, 0]] (Anyway, Python2 is no longer supported: link. I recommend you use Python3+NumPy, … Read more
You coded your program a bit awkwardly. However, that aside, you can get your method to output by using the print statement as opposed to the return. Otherwise, when you return something from a function you need to assign what is returned to some variable(s). For example: def getter(): return “Hello, world” r = getter() … Read more
You could add an additional check like this if (isinstance(value, list) and 5 in value) or value == 5: print “Yes for ” + key else: print “No for ” + key 7 solved Why does A resolve true, but B does not? [closed]
I think the problem is in the part where you insert your item into the cartList. You only insert the item, not the money with it. So in the return part, it must be: if ask == ‘return’: ret = input(‘What item do you want to return?\n’) for i in cartList: if ret==i: … Or … Read more
Could you have been thinking of something like this? def isPrime(n): if n < 2: return None factors = [ i for i in range(2, n) if n%i == 0 ] return True if not factors else False print( [ i for i in range(1, 100) if isPrime(i) ] ) #PRINTS: [2, 3, 5, 7, … Read more
