我在用破折号分割熊猫系列时遇到问题:

df['age'].head()

75)[1]Reichenberg, Sudetenland, Germany (present-day Liberec             
52) orJanuary 20, 1967 (age 51)(sources differ                                             
45–46                                                                                      
40–41                                                                                      
52)St.Thomas, Virgin Islands (United States of America  

申请时:

df['age'] = df['age'].str.split(')', n=1, expand=True)[0]

我正确地得到:

df['age'].head()

75           
52                                           
45–46                                                                                      
40–41                                                                                      
52

但是当我尝试用破折号分割时,它不会分割结果:

df['age'] = df['age'].str.split('-', n=1, expand=True)[0]
df['age'].head()

75           
52                                           
45–46                                                                                      
40–41
