[英]Converting text file to YAML in Python
我有一個要轉換為 YAML 格式的文本文件。 這里有一些注釋可以更好地描述這個問題:
格式示例如下:
file_content = '''
Section section_1
section_1_subheading1 = text
section_1_subheading2 = bool
end
Section section_2
section_2_subheading3 = int
section_2_subheading4 = double
section_2_subheading5 = bool
section_2_subheading6 = text
section_2_subheading7 = datetime
end
Section section_3
section_3_subheading8 = numeric
section_3_subheading9 = int
end
'''
我嘗試通過以下方式將文本轉換為 YAML 格式:
Section section_name
替換為section_name:
。end
。但是,我對#2 和#3 有困難。 這是迄今為止我創建的文本到 YAML function:
import yaml
import re
def convert_txt_to_yaml(file_content):
"""Converts a text file to a YAML file"""
# Replace "=" with ":"
file_content2 = file_content.replace("=", ":")
# Split the lines
lines = file_content2.splitlines()
# Define section headings to find and replace
section_names = "Section "
section_headings = r"(?<=Section )(.*)$"
section_colons = r"\1 : "
end_names = "end"
# Convert to YAML format, line-by-line
for line in lines:
add_colon = re.sub(section_headings, section_colons, line) # Add colon to end of section name
remove_section_word = re.sub(section_names, "", add_colon) # Remove "Section " in section header
line = re.sub(end_names, "", remove_section_word) # Remove "end" between sections
# Join lines back together
converted_file = "\n".join(lines)
return converted_file
我相信問題出在for
循環中 - 我無法弄清楚為什么部分標題和結尾沒有改變。 如果我對其進行測試,它會完美打印,但線條本身並沒有保存。
我正在尋找的 output 格式如下:
file_content = '''
section_1 :
section_1_subheading1 : text
section_1_subheading2 : bool
section_2 :
section_2_subheading3 : int
section_2_subheading4 : double
section_2_subheading5 : bool
section_2_subheading6 : text
section_2_subheading7 : datetime
section_3 :
section_3_subheading8 : numeric
section_3_subheading9 : int
'''
我寧願將其轉換為 dict 然后使用 yaml package 將其格式化為 yaml yaml
import yaml
def convert_txt_to_yaml(file_content):
"""Converts a text file to a YAML file"""
config_dict = {}
# Split the lines
lines = file_content.splitlines()
section_title=None
for line in lines:
if line=='\n':
continue
elif re.match('.*end$', line):
#End of section
section_title=None
elif re.match('.*Section\s+.*', line):
#Start of Section
match_obj = re.match(".*Section\s+(.*)", line)
section_title=match_obj.groups()[0]
config_dict[section_title] = {}
elif section_title and re.match(".*{}_.*\s+=.*".format(section_title), line):
match_obj = re.match(".*{}_(.*)\s+=(.*)".format(section_title), line)
config_dict[section_title][match_obj.groups()[0]] = match_obj.groups()[1]
return yaml.dump(config_dict )
