Introduction List comprehension is a powerful tool in Python that allows you to quickly and easily convert a for loop into a single line of code. This can be especially useful when dealing with large datasets or complex operations. In this article, we will discuss how to convert a for loop into a list comprehension … Read more
I’m not comfortable with Django, so I show a couple of option in plain Python, given the collections: something1 = [1,2,3,4] something2 = [1,2,3,4,5,6,7,8,9,10] You can access objects by index (not the same as database index): i = 1 for e1 in something1: print(e1) i += 1 for i2 in range(i,len(something2)): print(something2[i2]) Or slice the … Read more
Is this what you are after? >>> d=[] >>> while(True): … s=raw_input() … if s==””:break … temp = [s] … d.append(temp) … a,b,7-6,7-6,6-3 c,d,7-4,7-6,6-2 e,f,6-4,7-6,6-2 >>> d [[‘a,b,7-6,7-6,6-3’], [‘c,d,7-4,7-6,6-2’], [‘e,f,6-4,7-6,6-2’]] This makes a list item out of the input and then appends that list to your main list d You now should be able to … Read more
The default install location for Python-2.7 on Windows is: C:\Python27 Therefore you can: c: cd \Python27 python 5 solved Python 2.7.5 – Where is it installed on Windows Vista? [closed]
Your impression is correct, it’s not needed (unless of course you import print_function von __future__!). However, it’s not prohibited either. print is followed by an expression, and (sys.version) is a valid expression as much as sys.version is. Note that (x) does not create a tuple containing x (that would be (x,)). solved 2.7.6 python version … Read more
You don’t need the functions nor the sum or multiply variables, just put the operation in str.format(), and you were missing the last position. # def addition(num1,num2): # return num1+num2 # def multiplication(num1,num2): # return num1*num2 print(“1.addition”) print(“2.multiplication”) choice = int(input(“Enter Choice 1/2”)) num1 = float(input(“Enter First Number:”)) num2 = float(input(“Enter Second Number:”)) # sum … Read more
The Best answer is from Yousaf . x = [“apple”, “banana”, “carrot”, “cheese”, “pear”] print(“\””+’s ‘.join(x[:-1])+”s”+” and “+(x[4])+”s”+”\””) solved How removing commas in a list with strings, write in one line of code [duplicate]

This should do it: My_DICT = {‘Sale_Type’ : ‘Car’, ‘Sale_Length’ : 5, “Query_String” : “”} My_DICT[‘Query_String’] = “select * from Sales where Length > %s” % My_DICT[‘Sale_Length’] — EDIT — Considering your input example, you have a list of dictionaries in My_DICT. You could do it like this: for element in My_DICT: element[‘Query_String’] = “select … Read more
You’re not calling your main() function anywhere. Try adding main() before the final raw_input line. Also, your whitespace seems to be a bit messed up from where you copied to stack overflow. For example, the return s line should be inside the bubblesort function. Another mistake is that, for the line print “Your input: ” … Read more

Python 2 tries to provide a sort order for almost everything; dictionaries are no exception. Dictionaries are arbitrarily but consistently ordered when compared to one another to ensure that you can sort a heterogenous list that contains them. You should not derive any meaning from their comparisons, really. Python 3 abandoned the notion that all … Read more
you end the if block in the previous line when put a instruction at the same level indentation that the if statement if condition: stuff something # doing this close the if block and a elif can only happen in a if block and you do that in if row_count == 0: for i in … Read more
N1 is simply just a list of names (that are of type String). When you loop / iterate over your list (for names in N1), each loop iteration will then act on that index of the list. So for the first iteration of the loop, names is equal to Ryan and therefore since you are … Read more
No, you cannot have exactly that. However, if there some reason why you really need to have a string at the beginning of a line (and note that this not a recommended style at all in Python), you can write: ”’ This line is imperative: ”’; x = 5 Note the ; after the string. … Read more
