Python 2.7文本文件数据处理求助：格式化输出姓名与出生日期

Alright, let's break this down to get exactly the output you want. First, let's assume your text file (let's call it birth_data.txt) has the raw data as a single line of space-separated values:

Orville Wright 21 July 1988 Rogelio Holloway 13 September 1988 Marjorie Figueroa 9 October 1988

Here's a Python 2.7 script that reads this file, processes the data, and prints the formatted output in the shell:

# Open the text file and read its content
with open('birth_data.txt', 'r') as file:
    # Split all content into a list of individual strings
    data = file.read().split()

# Group the data into chunks of 5 elements (each chunk = [first_name, last_name, day, month, year])
people = [data[i:i+5] for i in range(0, len(data), 5)]

# Extract formatted names (First initial + last name) and birth dates
formatted_names = ["{0}. {1}".format(p[0][0], p[1]) for p in people]
birth_dates = ["{0} {1} {2}".format(p[2], p[3], p[4]) for p in people]

# Print the output in the required format
print "Name"
print " ".join(formatted_names)
print "Birth date"
print " ".join(birth_dates)

How this works: #

• Reading the file: We use with open(...) to safely open and read the file, then split the entire content into a list of strings using spaces as separators.
• Grouping data: Using list slicing (data[i:i+5]), we split the flat list into groups of 5 elements—each group represents one person's full name and birth date.
• Formatting names: For each person, we take the first character of their first name (p[0][0]), add a dot, then their last name.
• Formatting dates: We combine the day, month, and year elements from each group into a single date string.
• Output: We print the headers "Name" and "Birth date" followed by the formatted values joined into space-separated lines.

When you run this script in Python 2.7 Shell, you'll get exactly the output you specified:

Name
O. Wright R. Holloway M. Figueroa
Birth date
21 July 1988 13 September 1988 9 October 1988
