一个健壮的方法是使用tabulate：

# pip install tabulate

from tabulate import tabulate

print(tabulate(ii, tablefmt='plain', headers=list(ii)))

输出：

requirement
 0  hello all:. I request the following from you:

        do the laundry:
        sleep early
        wake up early
        feed the chicken

其他示例：

ii = pd.DataFrame({'A': ['123\nABCDE\n\n\nF', '12\n3'],
                   'B': [1, 2],
                   'C': ['ABC', 'A\nB\nC']})`

输出：

A        B  C
 0  123      1  ABC
    ABCDE

    F
 1  12       2  A
    3           B
                C

作为HTML

from IPython.display import display, HTML
display(HTML(ii.to_html().replace('\\n', '<br>')))

输出：
实施例1：

实施例2：

对齐

print(tabulate(ii, tablefmt='plain', headers=list(ii), stralign='left'))

        A    B    C
 0  123      1  ABC
    ABCDE

    F
 1  12       2  A
    3           B
                C

print(tabulate(ii, tablefmt='plain', headers=list(ii), stralign='right'))

        A    B    C
 0    123    1  ABC
    ABCDE

        F
 1     12    2    A
        3         B
                  C

您可以用途：

ii['requirement'].replace('\n', '', regex=True, inplace=True)

您可以用途：

import re

string=['''
    hello all:. I request the following from you:

    do the laundry:
    sleep early
    wake up early
    feed the chicken

     ''']
string = [re.sub('(\n+)(\s+)',' ',s).strip() for s in string]

ii=pd.DataFrame(string, columns=['requirement'])
ii
