Question

请告知我如何出现以下错误：

File "/Users/<username>/PycharmProjects/OOP/csv_write.py", line 8
  print(f'Column names are {", ".join(row)}')
                                           ^
SyntaxError: invalid syntax

代码：

import csv

with open('employee_birthday.txt') as csv_file:
    csv_reader = csv.reader(csv_file, delimiter=',')
    line_count = 0
    for row in csv_reader:
        if line_count == 0:
            print(f'Column names are {", ".join(row)}')
            line_count += 1
        else:
            print(f'\t{row[0]} works in the {row[1]} department, and was born in {row[2]}.')
            line_count += 1
    print(f'Processed {line_count} lines.')

我正尝试从文件中读取并按照the link如下显示信息。

employee_birthday.txt：

name,department,birthday month
John Smith,Accounting,November
Erica Meyers,IT,March

此问题已解决，感谢您的以下答复。

Answer 1

为此回溯所指的行尝试以下操作：

f字符串适用于py3.5及更高版本，请查看以下任一方法是否有效：

print('Column names are',", ".join(row))

OR

print('Column names are %s'%", ".join(row))

或

print('Column names are {}'.format(", ".join(row)))

Answer 2

请确保您使用Python >= 3.6，因为稍后介绍了f-strings。如果仍然不起作用，请检查代码的缩进。
