current_date = QDate.currentDate()

yesterday = current_date.addDays(-1)

date_edit.setDate(yesterday)

from PyQt5.QtWidgets import QApplication, QWidget, QDateEdit, QVBoxLayout
from PyQt5.QtCore import QDate

app = QApplication([])
window = QWidget()

layout = QVBoxLayout()
date_edit = QDateEdit()
layout.addWidget(date_edit)
window.setLayout(layout)

# 获取当前日期
current_date = QDate.currentDate()
# 计算昨天的日期
yesterday = current_date.addDays(-1)
# 将昨天的日期设置到QDateEdit控件中
date_edit.setDate(yesterday)

window.show()
app.exec_()
