python - 使用新行读取 csv 文件

Question

我想读取我创建的 CSV 文件，并将其打印在新行上:

这是代码

rows = []
with open("test.csv", 'r') as file:
    csvreader = csv.reader(file)
    header = next(csvreader)
    for row in csvreader:
        rows.append(row)
print(header)
print(rows)

我得到的输出是这样的......

['TeamName', 'MCount']
[[], ['team One', '23'], ['Team Two', '102'], ['Team Three', '44'], ['Team Four', '40']]

我希望它看起来像这样:

Team One 23    
Team Two 102    
Team Three 44    
Team Four 40

Answer 1

您可以遍历行并以您喜欢的格式打印每一行:

# For each row
for row in rows:
    # Make sure the row is not empty
    if row:
        # Print the row
        print(row[0], row[1])

或者，您可以使用列表理解将其全部作为字符串保存到变量中:

# For each row,
# if the row is not empty
# format it into a string.
# Join all the resulting strings together by a new line.
my_data_string = "\n".join([f"{row[0]} {row[1]}" for row in rows if row])
