好的，修改后的代码如下：

from supplier import* suppliers=[]

def pause():
input("回车继续：")

def supplierNew(suppliers):
supNo = input("新增供应商，请输入供应商编号：")
supName = input("供应商名称：")
supContact = input("联系方式：")
sup = Supplier(0, supNo, supName, supContact)
suppliers.append(sup)
pause()

def supplierDelete():
shan = input("请输入你要删除的供应商编号：")
p = 0
while p < len(suppliers):
if suppliers[p].supNo == shan:
print("要删除的供应商是：")
del suppliers[p]
p += 1
pause()

def supplierUpdate(suppliers):
chg = input("请输入准确的要修改的供应商编号：")
i = 0
while i < len(suppliers):
if suppliers[i].supNo == chg:
print("要修改的供应商是：", suppliers[i].getInfo())
supNo = input("修改供应商，请输入供应商编号：")
supName = input("供应商名称：")
supContact = input("联系方式：")
supId = suppliers[i].supId
suppliers[i] = Supplier(supId, supNo, supName, supContact)
i += 1
pause()

def supplierSearch(suppliers):
qry = input("请输入的查询内容：")
for sup in suppliers:
if sup.supNo.find(qry) >= 0 or sup.supName.find(qry) >= 0:
print("找到的供应商有：", sup.getInfo())
pause()

def clean():
i = 0
while i < 15:
print()
i += 1

menus = ["供应商管理系统：-----",
"1.新增供应商",
"2.显示已有供应商",
"3.查找供应商",
"4.修改已有供应商",
"5.删除已有供应商",
"0.退出",
"-------------"]

def supplierMgrDo():
while True:
clean()
for m in menus:
print(m)
sel = input("请输入一个整数，选择要完成的功能：")
if sel == "0":
break
elif sel == '1':
supplierNew(suppliers)
elif sel == '2':
supplierSearch(suppliers)
elif sel == '3':
supplierUpdate(suppliers)
elif sel == '4':
supplierDelete()

supplierMgrDo()
