  True

> "\"" in dfTrain['name']

How to check if a character is in the string list?

Answer 1

There may be several ways:

1) One of the things you can do is

"\"" in dfTrain['name'].to_string()

This returns Trueif any of the names in df contains ".

2) Another way could be not dfTrain[dfTrain['name'].str.contains('"')].empty

, , ". , ", , dataframe . dataframe (True), ", , "False" (, "" )

Answer 2

"\" " dfTrain ['name'] [22] - " , "Annie", "\"

dfTrain ['name'] - , "\"

:

>>> nested_list_example = ["abhishek","ralesh","wr'"]
>>> "wr'" in nested_list_example
True
>>> "'" in nested_list_example
False
>>> "'" in nested_list_example[2]
True

join() contains(), , ":

In [11]: df
Out[11]:
                                      name
0                           [test1, test2]
1                           [another test]
2                      [yet, another test]

Out[12]:
0    False
1    False
