行间问题-运行PyLyrics时的NaN输出
行间问题-运行PyLyrics时的NaN输出
提问于 2020-01-24 17:55:49
我正在为一个使用PyLyrics的项目制作歌词数据集。
我已经导入了dataset，安装了PyLyrics，现在尝试让Python为dataset中的所有行生成歌词，但它没有提供任何输入。
import pandas as pd
data = pd.read_csv(r'C:\Users\kk\Desktop\dba lyrics analysis\all_periods_joined_for_lyrics_1.csv', header=1)
df=pd.DataFrame(data, columns=['Position', 'Track Name','Artist','Streams','date','period'])
for index, row in df.iterrows():
try:
from PyLyrics import *
df.loc[index, 'Lyrics'] = PyLyrics.getLyrics(row['Artist'], row['Track Name'])
except:
pass当我到达print(df)时，输出是用我的头和'NaN‘填充的表，而不是任何输出。此外，歌词列也不会生成。
我该怎么办？
我是编程新手，但论文很快就要完成了，所以我非常感谢大家的帮助！
提前感谢！

我可以想象，将PyLyrics导入到try-except块中会掩盖这样一个事实，即PyLyrics模块没有安装在您的计算机上，因此无法导入：
try:
from PyLyrics import *
except:
# If the import failed we can fix it here - but we just ignore it (pass)
pass相反，将from PyLyrics import *放在没有try-except块的文件开头，这样如果没有安装包，脚本就会立即失败。在这里看看如何安装这个包：https://pypi.org/project/PyLyrics/。
下面的代码非常适合我。
from PyLyrics import PyLyrics
from pprint import pprint
from pandas import read_csv
songs = read_csv('songs.csv', header=None, names=['Artist','Title'])
for index, row in songs.iterrows():
print('Getting lyrics for', row.Artist, row.Title)
try:
lyrics = PyLyrics.getLyrics(row.Artist, row.Title)
except:
lyrics = None
print('Failed to get lyrics for', row.Artist, row.Title)
songs.loc[index, 'Lyrics'] = lyrics
pprint(songs)
