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) solved Getting an error while … Read more

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 solved Python iterate over multi value nested dictionary [closed]
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 9999th … Read more

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 solved A python’s beginner exercise [closed]
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 solved Python – trying to replace a text string that contains “”
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 file2 … Read more
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 solved Object detection realtime using tensorflow
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 can … Read more
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) so … Read more

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 the … Read more
