使用 pandas 删除句子后面/里面的所有内容

Question

I have a csv file containing sentences that some has / in like shown in the picture

I'm trying to go though all sentences and whenever a / comes just remove what every comes after it ny expected output is something like that

what I tried until now is finding the slashes but how to remove what comes after them.

tdata = pd.read_csv(fileinput)

pat = '[' + re.escape("/") + ']'
df=tdata[tdata['sentences'].str.contains(pat, regex=True, na=False)]

Answer 1

Use Series.str.split with one or no spaces \s* and / and then select first lists by str[0] :

tdata['English'] = tdata['English'].str.split('\s*/').str[0]

Or you can remove possible whitepaces after by Series.str.strip :

tdata['English'] = tdata['English'].str.split('/').str[0].str.strip()
