[ad_1] You can’t send the whole Pandas dataframe into cv2.imread. You want to access the actual file itself. You also want to append with the image, not a list containing just the image to allow for easier accessing: data = [] for i in range(len(train_data)): img_array = cv2.imread(train_data.loc[i, ‘file’], 1) data.append(img_array) [ad_2] solved Getting an … Read more

[ad_1] First iterating over the outer values using key_level1 and val_level1, then iterating over inner values using key_level2, val_level2: for key_level1, val_level1 in r.items(): for key_level2, val_level2 in val_level1.items(): for val in val_level2.split(‘,’): # Example: # do something print(key_level1, key_level2, val) 4 [ad_2] solved Python iterate over multi value nested dictionary [closed]
[ad_1] While I agree with many of the other comments here I figured I’d throw a bone. The decimal module is a utility for doing arithmetic on numbers of arbitrary precision. This is used in some scientific contexts to do calculations on things that suffer from round-off errors. The classical example would be calculting the … Read more
[ad_1] Put it into a class like: class fruit: a = 0 def apple(self): self.a = 2 def orange(self): if(self.a == 2): print(‘your fruit is apple’) a = fruit() [ad_2] solved how to use function’s variable in another one python
[ad_1] What you need here is to print space 70 times minus the length of your string, then your string. print (‘ ‘*(70-len(s))+s) 4 [ad_2] solved A python’s beginner exercise [closed]
[ad_1] As you have already found out, regex can do the job pretty easily: import re filedata=”minRequiredPasswordLength=”9″” r=”11″ result = re.sub(r’minRequiredPasswordLength=”\d*”‘, r’minRequiredPasswordLength=”{}”‘.format(r), filedata) print(result) >>>> minRequiredPasswordLength=”11″ 0 [ad_2] solved Python – trying to replace a text string that contains “”
[ad_1] A simple function to extract the Nth column from your text makes this reasonably straight-forward. I’ve assumed when you say “Column 11” you mean, the 11 column counting from 1, not the index-11 column where the 1st item is index-0 Pseudo-Code: Until there’s no data left ~ Read line1 from file1 Read line2 from … Read more
[ad_1] A little google search would already help or just reading the Readme… You forgot to run this: #From tensorflow/models/ protoc object_detection/protos/*.proto –python_out=. 2 [ad_2] solved Object detection realtime using tensorflow
[ad_1] Now that you’ve fixed the original problem, and fixed the next problem with doing the check backward, and renamed all of your variables, you have this: for match in dictionary: if any(match in value for value in sentences): print match And your problem with it is: The way I have the code written i … Read more
[ad_1] Pip is a package manger for Python modules. The command pip freeze outputs all installed modules (including version numbers). The –local flag prevents Pip from printing globally installed packages in a virtual environment. Usually, a Python program depends on other modules. You can put those required modules in a text file (requirements.txt by convention) … Read more
[ad_1] def find_odds(numbers): if not numbers: return [] if numbers[0] % 2 == 1: return [numbers[0]] + find_odds(numbers[1:]) return find_odds(numbers[1:]) No extra variables or parameters needed. 7 [ad_2] solved How can I return the odd numbers of a list, using only recursion in Python? [closed]
[ad_1] When you initialize your variables playerX and playerY you don’t specify they are global, so the function is trying to set the value of a local variable that does not exist. To fix this at the beginning of your update_coords function add global playerX, playerY This tells the computer that playerX and playerY are … Read more
