2. Installation method
Can be installed through the pip toolpython-pinyinlibrary. Enter the following command on the command line:
pip install pypinyin
3. Basic usage
- Import library：
from pypinyin import pinyin, lazy_pinyin, Style
- Convert Chinese characters to pinyin：
# Normal styleresult = pinyin('China', style=)
print(result) # [['zhong'], ['guo']]
# tone styleresult = pinyin('China', style=Style.TONE2)
print(result) # [['zho2ng'], ['guo2']]
# First letter styleresult = pinyin('China', style=Style.FIRST_LETTER)
print(result) # [['z'], ['g']]
- Convert Chinese name to pinyin：
# Lazy loading method, suitable for long text or memory-saving scenariosresult = lazy_pinyin('Wang Xiaoming')
print(result) # ['wang', 'xiao', 'ming']
- Processing polyphonic characters：
# Enable polyphonic moderesult = pinyin('Chongqing', heteronym=True)
print(result) # [['chóng', 'qìng'], ...] All possible pronunciations for "chong" and "qing"- Custom pinyin style：
# Custom pinyin style requires inheriting the Style class and defining CUSTOM_STYLEclass MyStyle(Style):
CUSTOM_STYLE = 99
# Use custom styleresult = pinyin('China', style=MyStyle.CUSTOM_STYLE)
# Note: Here you need to implement the custom style, otherwise you will not be able to use the custom style.4. Advanced functions
- Load custom dictionary：
# Define custom dictionarycustom_dict = {'Double Ninth Festival': [['chóng'], ['yáng']]}
# Load custom dictionarypypinyin.load_phrases_dict(custom_dict)
# Convert with a custom dictionaryresult = pinyin('Double Ninth Festival')
print(result) # Pinyin results output according to custom dictionary- Pinyin annotation：
# Pinyin annotation of texttext = "Pinyin Annotation Example" pinyin = pinyin(text, style=) annotated_text = ' '.join([''.join(item) for item in pinyin]) print(annotated_text) # Pinyin mark results, such as "pīn yīn biāo zhù shì lì"
