python - TypeError：预期的字符串或类似字节的对象 Tqdm

问题描述

关于这个问题，我已经在 stackoverflow 中查看了几个来源，但无法解决。所以我把它贴在这里，请解决。

# Combining all the above statemennts 
from tqdm import tqdm
Other_skill = []
# tqdm is for printing the status bar
for sentance in tqdm(project_data['Other skills'].values):
    sent = decontracted(sentance)
    sent = sent.replace('\\r', ' ')
    sent = sent.replace('\\"', ' ')
    sent = sent.replace('\\n', ' ')
    sent = re.sub('[^A-Za-z0-9]+', ' ', sent)
    sent = ' '.join(e for e in sent.split() if e not in stopwords)
    Other_skill.append(sent.lower().strip())

错误：

解决方案

我认为 values() 中的括号是需要的。如果我是正确的 project_data 是字典，而您错过了值中的括号

from tqdm import tqdm
Other_skill = []
# tqdm is for printing the status bar 
# the values must have round brackets
for sentance in tqdm(project_data['Other skills'].values()):
    sent = decontracted(sentance)
    sent = sent.replace('\\r', ' ')
    sent = sent.replace('\\"', ' ')
    sent = sent.replace('\\n', ' ')
    sent = re.sub('[^A-Za-z0-9]+', ' ', sent)
    sent = ' '.join(e for e in sent.split() if e not in stopwords)
    Other_skill.append(sent.lower().strip())
